Build fixes.

Remove spurious dependency on zlib1.dll since we never actually build it.
Instead use the static lib that we *do* build.

Clean up project64.vcxproj file to elminate redundant conditions and
factor out common settings.
Fix Glide64 build and normalize line endings.

The VCXPROJ file was referencing the retail versions of the libs and hence
couldn't find them. Fix by having two sets of wx lib names: debug and rtl.

Also, cleaned up the vcxproj.
