osx: fix annoying focus behaviour (#689)
OS X has a global menu bar and a per app dock icon. Therefore, all
GUI applications launched from a terminal will become focused - even
if they don’t show any windows. Thereby the terminal loses focus.
Since is it very annoying to re-focus the terminal after each proxmark
client launch, this change makes the client unfocusable during launch
and restores the regular behaviour when a window is created.

osx: disable app-nap during serial comm (#687)
Apple introduced app-nap with OS X 10.10. This feature
saves power by throttling apps running in background.
However, it also less accurate timers in systemcalls. In
our case a 30ms select timeout would take up to 10s.
This patch uses an API also added with 10.10 to disable
app-nap as long as the serial port is polled.

* FPGA Hi-Simulate: Added 212kHz SSP-Clock option
* Legic: Moved card simulator into separate file & cleaned interface.
Reader and card simulation have almost no common code. Moreover the sim
uses an SSP Clock at 212kHz for all timings to prevent any drifting from
the PRNG. This clock speed is not available in reader simulation mode (SSP
runs at up to 3.4MHz, and changes speed between TX and RX). For these
reasons having the code in separate files makes it significantly cleaner.

lf hid improvements - encoding and long tag simulation
**DEVICE FIRMWARE UPDATE**
The code changes needed to support long tag emulation required an update to the device firmware. As of this patch, devices running older firmware will not be able to read or emulate HID tags until the firmware is updated. Additionally, devices with the firmware from this update or newer will not properly read or encode HID tags with a prior version client.
The 'lf hid encode' command has been further refined, and is now entirely parameterized to support use of fields other than facility code and card number. The client help data has been updated to show the correct syntax.

Redesign of lf hid card format handler as discussed with @marshmellow42
The new handler accepts multiple formats of the same length.
Because of this, the existing pack/unpack commands are unsupported
and have been removed and replaced with 'lf hid encode' and 'lf hid decode'.
The decode command will test a packed Prox ID against all programmed
formats and return results for all matching formats.
The encode command takes the parameter of format name instead of
bit length (as per the old pack command). Additionally, an 'lf hid write'
command has been added as a single-command combination of encode and clone.
To support easier addition of new formats, a library for handling card
fields has been added. This will allow direct access to the card bits,
to linear fields, and to non-linear (jumping) fields in a single line
of code without having to resort to managing bit positions or masks
on the underlying data. A number of new formats have been added as working
examples of the new support functions.

Legic: rewrite reader to use xcorrelation and precise timing (#654)
* Legic: rewrite reader to use xcorrelation and precise timing
- Even tough Legic tags transmit just AM, receiving using
xcorrelation results in a significantly better signal
quality.
- Switching from bit bang to a hardware based ssc frees
up CPU time for other tasks e.g. prng and demodulation
- Having all times based on a fixed ts, results in perfect
rwd-tag synchronization without magic +/- calculations.
* hi_read_tx: remove jerry-riged hysteresis based receiver
- This feature got obsolete by a x-correlation based receiver.
* Legic: adjusted sampling to new ssp clock speed
- Sampling is 4 times faster and pipeline daly reduced to 1/4.
The new code samples each bit earyler to account for the
shorter pipeline. That introduced bit errors by leeking the
next bit into the current one.
* Legic: average 8 samples for better noise rejection.
* Update CHANGELOG.md

fix: 32bit tick timer based on TC0 and TC1 (#653)
TC1 counts the number of TC0 overflows (carry bits).
In random conditions TC1 would return or stay at zero,
instead of counting up. This due to the behavior of the
reset signal.
SAM7S Series Datasheet, 33.5.6 Trigger:
Regardless of the trigger used, it will be taken into account
at the following active edge of the selected clock. This means
that the counter value can be read differently from zero just
after a trigger, especially when a low frequency signal is
selected as the clock.
The new code first prepares TC1 and asserts TC1 trigger and
then prepares TC0 and asserts TC0 trigger. The TC0 start-up
will reset TC1.
