Landing a log of AppleScript/AppleEvent support code.

Landing GTMHTTPServer as a simple server but mainly for use in unittesting.
_GTMCompileAssert for doing compile time assertions to GTMDefines.h
Lots of improvments for UnitTesting, Dave's gonna put up a wiki page shortly with the full details of what can be done.

+// _GTMCompileAssert is an assert that is meant to fire at compile time if you
+// want to check things at compile instead of runtime. For example if you
+// want to check that a wchar is 4 bytes instead of 2 you would use
+// _GTMCompileAssert(sizeof(wchar_t) == 4, wchar_t_is_4_bytes_on_OS_X)
+// Note that the second "arg" is not in quotes, and must be a valid processor
+// symbol in it's own right (no spaces, punctuation etc).
+
+// Wrapping this in an #ifndef allows external groups to define their own
