Fix travis ci tests

I was looking into why Travis CI fails and there are some things that need to be fixed. Maybe someone has some ideas. I fixed the jQuery, Cheerio, Logg, Modernizr, MsNodeSql, Node_Redis, PouchDB, Restify, Scroller
_EDIT 1:_ Also fixed Sugar, Backgrid, jQueryUI

Syntax checking:
-------------------------

ExtJS: 
- bool should be changed to boolean
- a lot of "Overloads cannot differ only by return type" errors
- some "cannot extend interface....types are incompatible" errors

Intl:
- I think this extension should be removed because Intl is defined in lib.d.ts already

Sencha_Touch: 
- same as ExtJS

Sugar:
- some strange stack overflow error (could be a bug in tsc)

Typing tests:
-----------------

Backgrid:
- needs "--target ES5" compiler parameter

Ember:
- lots of errors

Intl:
- I think this extension should be removed because Intl is defined in lib.d.ts already

jQueryUI:
- compile error in lines 1092 and 1140 caused by https://typescript.codeplex.com/workitem/1522

jsDeferred:
- lots of errors

SammyJS:
- lots of errors

Sencha_Touch:
- lots of errors related to type definition errors

ThreeJS:
- using some webkit... and moz... properties resulting in lots of "property ... does not exist on value of type"
