Subject: [PATCH] Inclusion of unused oem variable
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

When compilation of the current source code, I am getting the warning of setting the unused variable "oem". I have included this, along with minor spelling corrections/language updates in the menu system.

gcc -std=c99 -O3 -mpopcnt -march=native -g -I. -I../include -I../common -I../zlib -I/opt/local/include -I../liblua -Wall -DHAVE_GUI -DZ_SOLO -DZ_PREFIX -DNO_GZIP -DZLIB_PM3_TUNED  -c -o obj/cmdlfhid.o cmdlfhid.c
cmdlfhid.c: I funktion "CmdHIDWiegand":
cmdlfhid.c:292:11: varning: variabeln "oem" sätts men används inte [-Wunused-but-set-variable]
  uint32_t oem;
           ^

Before:
pm3 --> lf hid wiegand 0 101 2001
HID 26 bit | FC: 101 CN: 2001 | Wiegand Code: 0000002004CA0FA2
[...]
HID 40 bit | FC: 101 CN: 2001 | Wiegand Code: 0000000000000FA2

After:
pm3 --> lf hid wiegand 0 101 2001
HID 26 bit | OEM: 0 FC: 101 CN: 2001 | Wiegand code: 0000002004CA0FA2
[...]
HID 40 bit | OEM: 0 FC: 101 CN: 2001 | Wiegand code: 0000000000000FA2
