Renamed the C# implementation to MetaIIinCSharp

Keeps our formats seperate so they're easier to work with, and set the
  class to inherit the Compilers base class from the rest of the
  project.
Added MetaCompiler project

Includes an empty console app (exciting?), Compilers class the other
  compilers will inherit so we can call them generically, and a copy of
  the Meta II compiled to C# code by the workshop's javascript code.
