Moved Ruby execution into its own project

Took out all the IronRuby-specific stuff and created a script-agnostic
project which allows you to run arbitrary scripts (currently just .rb).
Mostly formatting and parsing improvements
Some changes while trying (and scrapping) JS support

- ScriptRunner invokes with script, not script name
- Added test project. Tests are coming.
Integrated ClearScript + Tests

- Added infrastructure for Javascript content
- Added test: creating a command from Javascript
- Added work-around for array type conversions (will work for Ruby too?)
- Added a bunch of Ruby tests too
Ruby auto header injection and to string array

- Common ruby header code is now auto-included from common.cs
- Ruby arrays can be converted to string arrays automagically now
- Added ScriptHelper for language-agnostic methods (just two so far)
- Moved Area into common; the Game is quite lightweight now.
- Renamed main script runner class to "Runner"
- Filled out JS tests
- Removed boilerplate code from JS and RB files
