Javascript Region Folding

See [Discussion] (https://groups.google.com/forum/#!topic/ace-discuss/JkeDqTJAUso)

*Harutyun Amirjanyan: but since vs and webstorm support i am not opposed to including it (either default or as an extension) if required changes are small
create the pull request and i'll have a look.*
I'm not exactly sure what you mean here. 
When the widget is folded it should only display:
`#region [description] [fold widget]`

Anything on the `#endregion` line should not be displayed (when folded) including anything after `#endregion` such as `#endregion test`
