Fixed CTests bugs, minor plugin enhancements, and removed old files

- Fixed incorrect message buffer size in sendCTRL function.
 - Fixed a bug in sendCTRLTest where not all DREF sizes were being set.
 - Increased message buffer size in sendReadTest to account for assumptions made by sendUDP.
 - Fixed a bug in updateLog where the log message would sometimes start with several null characters, causing the log message to be effectively ignored by fprintf.

 - The xpcPlugin Visual Studio solution now supports 32 bit and 64 bit builds.
 - Logging performed by the plugin now works correctly on Windows.
 - Long log messages are now truncated to 500 characters. Previously, messages over 500 characters would be omitted, and an error message logged in their place.

 - Several files which were incorrectly added to source control have been deleted.
