Update OS X compilation instructions

- GCC 4.8+ is now required - remove references to 4.5, XCode 7, etc.
- Homebrew's formula has been renamed to "gcc@4.8". "gcc48" still works as well,
  so applying this change to the master branch isn't urgent.

DFHack can officially be built on OS X with anything from GCC 4.5 to 4.8, so 4.8
is recommended, as 4.5 has issues on newer systems, but 4.5-4.7 should also
work. Anything newer than 4.8 will require you to perform extra steps to get
DFHack to run (see `osx-new-gcc-notes`), and your build will likely not be
redistributable.

If you try to build with GCC 4.5, you will probably find that GCC 4.5 will fail
to install on OS X 10.11 and newer, or any older OS X that is using XCode 7 or
newer. There are two workarounds:
* Install a newer version of GCC instead (e.g. ``brew install gcc48`` or ``brew
install gcc5``) and follow the instructions for linking libstdc++ below.
* Install XCode 6, which is available as a free download from the Apple
Developer Center.
* Either install this as your only XCode, or install it additionally
to XCode 7 and then switch between them using ``xcode-select``
* Ensure XCode 6 is active before attempting to install GCC 4.5 and
whenever you are compiling DFHack with GCC 4.5.
If you build with a GCC version newer than 4.8, DFHack will probably crash
immediately on startup, or soon after. To fix this, you will need to replace
``hack/libstdc++.6.dylib`` with a symlink to the ``libstdc++.6.dylib`` included
