Revamp the build system.

This achieves several goals:

 * Less reliance on scripts so we have better portability to Windows
   (though we still have a ways to go for proper Windows support).
   Luajit, luarocks, moonscript, and busted are all installed via CMake
   now.
 * Trying to make use of pkg-config to get the correct libraries.  The
   latest libuv is still broken in this regard, but we'll at least be in
   a position to use it.
 * Allow the use of Ninja or make.  The former runs faster in many
   environments, and automatically makes use of parallel builds.

This also allows for system installed dependencies--though not through
the Makefile just yet--and adds support for FreeBSD.

This also make us build libuv and luajit as static libraries only, since
we're only concerned about having static libraries for our bundled
dependencies.
