WIP: resizing columns
Only build 3.0 branch on travis, not 3.0 feature branches
Merge branch '3.0' of https://github.com/angular-ui/ng-grid into 3.0
u18n was failing compilation and jshint tests

1. If checks need to have curly braces
2. arguments.callee is deprecated, and forbidden in strict ECMA5. Replaced

Column resizing works
WIP: column resizing
WIP: column resizing

Had to alter style computation so they can specify a priority. Also added
a refresh function to the resizer that forces a scroll event so we don't
run into a weird issue where the scrollbar is extending beyond the
viewport and causing offsets between the header canvas scrollLeft and body
canvas scrollLeft.

Right now the offsets don't occur but the horizontal scrollbar DOES extend
3px beyond the right viewport if you scroll all the way to the right and
then resize a column smaller than it was.  Need to fix that.
WIP: trying to get horiz. scrollbar to move into the right place, post column resize
WIP angularized ui18n  - need unit tests
Fix: horiz. scrollbar updates correctly on column resize
Fix: elmMaxBound() and getElmSize() being stored on 'this' in link() was a terrible idea, and broken
Turn off building 3.0 feature branches
i18n fixes and tests
