Updated syntax/language constructs, as discussed today
Added list of language constructs
Fixed typo
retry push dsl
Separated user code and gamel implementation code
Still implements toy code
This is a possible implementation for define
Completed a simple toy implementation of scene, entity definition
    and instantiation, inspired by Tianyu's version.
Added scenes and instantiation
Added some syntax to simplify implementation
-Split libgamel.scala into the gamel package and subdirectory for
better organization and modularity. The user just needs to

    import gamel._

Unfornately, it means that you can only build from the top directory:

    (cd ../..; sbt compile)

-Added -language:implicit to build.sbt to remove compile warning.
Update GamelMain.scala

Removed extra import
Update README.md
Added action construct to language

Made most of gamel package protected to reduce namespace complexity
and give the user a uniform interface with no cluter
Merge branch 'proposed' of github.com:gamel/gamel into proposed
