Move to ts

Proposed changes

The objectives of this first step was:

• just convert all files to typescript maintaining everything as is and with minimal changes in the code so it can be quickly revie (this means I have not dedicated to try add all type definitions, just the ones automatically added and some required ones.)
• update the grunt process to use webpack instead of babel, but again maintaining everything as simple as possible.

Pending tasks

1. Tests: There are about 3-4 test that I cannot get to work. I think I have been able to fix the tested functionality, but not in the test. As I have not been able to debug the tests is difficult for me to found the reason.
2. Complete types for components. Add types for every component option.
3. Someone who knows better the framework should check that grunt processes work completely as expected and a complete checking that components can we loaded and works just as before.

Oh I somehow could not add any merge commits here because your v2-dev branch was deleted 😄
I hope I get the missing tests to work!
