Sym-links for typescript and a sublime_text project file

* Use symbolic links for typescript-src directory: faster and allows better editor support. 
* Cleanup names in Gruntfile
* Added a editor_support directory and put in a project file for sublime_text (provides a folder view of src and typescript-src, the latter allows correct in-editor as-you-type checking with references resolving correctly)

Tested: 
open `sublime_text` (I'm using [version 3](http://www.sublimetext.com/3)), From menus: 
 1.  Install sublime_text 3 and the T3S package.
 2. `Project -> Open Project...`  
 3. Select the `editor_support/sublime_text/uproxy-lib.sublime-project` file.
 4. Edit the typescript, make an error, fix it.
