Build with -msse3 on OS X. The first Intel Macs were Core Duo/Solo, which

had SSE3. Keep -msse2 on other platforms. Not sure if there are actually
any Dolphin-capable machines out there without SSE3, but..

Use -search_paths_first to give our statically linked libraries precedence
over /usr/local/lib. 

Some work-in-progress changes to facilitate a more easily redistributable
application bundle on OS X.

Group compiler/preprocessor/linker flags together to make the full set
more intuitively apparent.

The various libraries in Externals have rather inconsistent conventions
for include paths. Best to encapsulate that knowledge in foo/SConscript.

Re-use utils.GenerateRevFile for all three places in the build system 
where we need the SVN revision number.
