Bug 33417: Create standard toolbar component

This commit introduces a standard Toolbar component that can be used
throughout ERM

Test plan:
1) Apply patch
2) Navigate to Agreements and click the "Add agreement" button - this
   should work as normal
3) Navigate to Licenses and repeat
4) Navigate to Local packages and repeat
5) Navigate to local titles - there should be two buttons, one to add and
   one to import. These should work as normal
