FORGEPLUGINS-156 Use Forge 1.4.3 as a test dependency.

Forge 1.4.0 is still used as the API dependency so as to not break JBDS
Upgrade Forge API to 1.4.3.Final
FORGEPLUGINS-155 Upgraded to Bootstrap 3

The generated scaffold now uses Bootstrap 3. This now has a mobile
first design - the side navigation bar works in a responsive
manner.

CSS classes no longer available in Bootstrap 3 have been
dropped. Tables are now responsive in nature - the support added
in the older scaffold is now dropped since it is available out of
the box in Bootstrap 3.
FORGEPLUGINS-137 Upgrade to AngularJS 1.2

This now ensures that AngularJS 1.2 is used in the generated
scaffold. The only major change is in the use of the AngularJS
ngRoute module.
