Gitignore now ignores dylib files as well
Updating local clang includes to 3.2

We have to have these beneath the folder where ycm_core.so is placed so that we
get fast completions. If these files are not here, then clang fails to
precompile a file preamble and completions are slow.
We now use @loader_path on Mac for libclang

This makes sure that our local copy of libclang.dylib is preferred over the
system one.
