[win32] remove redundant /MP compiler option in release builds.

The duplicate /MP option (listed in "Additional Options" and also enabled with the "Multi-processor Compilation" option) was causing a full rebuild because msbuild is removing the duplicate from the commandline causing:
"Forcing rebuild of all source files due to a change in the command line since the last build."

Revert "[airplay] - merge the binary plist and xml plist pathes in airplay (which already diverged) by using libplist for parsing in both cases - not only the binary case"

This reverts commit 392babec96915939f416efa6888e1379140ad725. Because it
was plain wrong - the text version of the airplay protocol is not even
XML.
