FPGA - allow long or short device names in detect code + style police

@@ -239,6 +239,7 @@ The official supplied binaries are compiled with support for all FPGAs.
 To force the code to only attempt detection with a specific driver,
 prepend the argument with the driver name followed by a colon.
 For example, "icarus:/dev/ttyUSB0" or "bitforce:\\.\COM5"
