Several updates to the get-mono.sh file:
- Now temporarily using my fork of mono, with a patch pre-applied. You
  can still specify a local checkout of mono if you wish.
- Now building using the master branch of mono (from my patched fork).
- Removed unnecessary configure options, like --with-moonlight=no.
- Now copying the monodroid assemblies into the install directory.
  mono's make install doesn't currently do this for you (and probably
  won't for the forseable future, as stated by devs).

This is a work in progress, and the actual binaries have not yet been
tested in a real application, and may not work.
