added functionality in Dash to search VIM, Bash and Vagrant

Paralleled previous functionality but with searches for Vagrant, Bash
and VIM. 

Provided transparent icons for each. Added iconography to each
folder. Updated versioning in json files to v1.22 and updated readme
with calls.

Connected back to the same Action.
