Fixed the broken tooltips.
fixes #512
As we cannot easily decouple from the Yii yet inserted the minimal code needed to instantiate Bootstrap component in real Yii environment.
Fixed the Bootstrap component initialization code to properly accommodate to being run under test harness.
Extracted code lumps from `Bootstrap.init()` to separate methods.
Changed the structure of tests a bit for phpStorm to correctly determine the class of `Yii::app()` call result.
Some more changes to structure of `Bootstrap.init()`.
Reformatting of code example in comments.
Replaced conditional with guard case and fixed error codes in `TbSortableAction`.
Added source information about `TbTags` widget.
Now the tests for `TbAlert` depend on global Yii::app() object, too.
Made the definitions for moment, select2 and x-editable plugins and replaced direct calls to its files in `TbEditableField`
Merge branch '1.1.0-wip' of github.com:clevertech/YiiBooster into 1.1.0-wip
