Add angular setup (#44)

Add angular setup

Update bower versions
Disable auto-open browser on grunt:serve task
Remove almost all autogenerated and useless files
Update translation usage: prefer attribute 'translate' over the filter: it fixes UI issue.

Note
- There was no need to update node depedencies versions due to
the use of ^ (last were already downloaded)
