refactor(code): Enforce single quotes

Well, I think that the more time we take to enforce some rules, the worst the work will be.

I want you all to have in mind that my Github experience is not that good so this is my opportunity to learn how to merge big big changes. Bear with me and please help me also (with the merging stuff, I can enforce this rule by my own :+1: ).

So far this is the status:

- [x] accordion
- [x] alert
- [x] bindHtml
- [x] buttons
- [x] carousel
- [x] datepicker
- [x] dropdownToggle
- [x] modal
- [x] pagination
- [x] popover
- [x] position
- [x] progressbar
- [x] rating
- [x] tabs
- [x] timepicker
- [x] tooltip
- [x] transition
- [x] typeahead

I am doing it for bottom to top, is how I get the feedback from `jshint`. So far I am doing all of this by hand, I hope I am not wasting my time if there is a better way :P (typeahead had a looot of changes).

Not all of them are broken, but there are a lot of errors and I can't see which of them are ok.

Any feedback is appreciated :D
