Fixes issue #174

Moved dl down in the link list for the PolycodePlayer and StandalonePlayer targets. See http://www.network-theory.co.uk/docs/gccintro/gccintro_18.html
Fixes behavior when WAV files aren't found.

Previously it'd just give an error message but not actually abort. Now it does the same as loadOGG does.
Removed redundant case.

The if just before already excluded that possibility.
Forgot to add the { } to the now 2-line if-block.

Silly me.
Removed .user files from .gitignore

Fixes issue #174
Merge pull request #183 from CIB/cleanup

Various code cleanups
Omnibus MinGW support patch: Updates to MinGW hacks block in CMakeLists. Updates to GLEE glue/exceptions in PolyGLHeaders, PolyGLSLShaderModule, PolyWinCore. Remove redundant gl includes in PolyWinCore.cpp. Include <ios> explicitly in windows PolycodeView. Omit multitouch support (code in PolycodeView, TUIO module) when compiling with MinGW. All targets other than MinGW+Windows should remain unchanged after bringing in these changes because everything's behind #ifdefs.
