* [LIBOMV-506] Complete rewrite of CapsBase to use HttpWebRequest instead of our homebrewed WebRequest hack. We lose the upload progress callback but gain IOCP thread instead of System.Thread usage and Keep-Alive support

* Content-Types described in http://tools.ietf.org/html/draft-hamrick-llsd-00 are used for CAPS requests. This *may* be incompatible with the current SL grid, needs testing
* Modified CapsClient requests to require OSDFormat enum and timeout values
