Added prompt for site-setup.sh to rebuild the databases of the core tools.

This works for now since if you run vagrant reload --provision the input of $dbinput will result in nothing.

Thus if you run ./site-setup.sh from the vagrant shell, it will prompt if you want to Rebuild or Nothing, typing Rebuild will drop and reimport the database tables.
rm /root/.ssh/config is 3 lines above already
Changed the prompt question/answer to be standard format

`What would you like to do with the databases? (yes/no)? [default: no]`
Merge branch 'master' into add/database-rebuild-choice
