In-progress fix to allow reprogramming of firmware in XuLA/XuLA2 boards.
Corrected comment that referred to another program.
+ Changed routines for reading FIFO levels since those are now sent as multi-word transmissions.
+ Added an option where receiving a data packet will always return a list even if only one word is requested.
Added utility that bridges a serial port over a USB link to an xscomm module running in a XuLA board.
Merge branch 'python' into gxstools_fixup
+ Enabled loading of .bit files into serial config flash.
+ Presence of use_local_xstools.py file now adds local XSTOOLs files to python path.
Updated to the new PIC 18F14K50 firmware.
Added command-line tool for setting/getting flags in XuLA/XuLA2 boards.
Rearranged location of bitstreams that interface to the XSTOOLs.
Added option for forcing return of a list even if only a single value is returned.
Added option for uploading/downloading the SDRAM on the XuLA boards.
+ Reset the comm link upon startup of the server.
+ Always upload everything the board has.
Distribute new version of XSTOOLs.
