Do not set C++ compiler explicitly in Xcode projects

LLVM-GCC is no longer available in Xcode 5 (on OS X 10.9).
Backport patch to remove strlcat from curl

Since strlcat is defined in OS X 10.9 as a macro, it collides with
the fallback definition in curl. I backported this fix from upstream
curl: http://curl.haxx.se/mail/lib-2013-02/0214.html

Originally I intended to update curl to a more recent version instead,
but I did not want to break the other platform builds.

Use GNU libstdc++ instead of libc++ on OS X
Removed TextDesigner offset flooring

I don't know if this is to help pixel alignment or something, but I don't run my game at a scale that is the same as the resolution, and with the varied devices that are out there I'm not sure many does? With a lower scale that flooring can move the text around big time, which it did for me :)
