Add automatic SDE updater script for Debian

Previous SDE updater doesn't work with Debian. This version works with
Debian and attempts to make the process of importing SQL files easier as
well.
Update SDE updater with flag and database check

Implemented a check in the SDE updater which checks for valid database
connections and add an option for users to not have it attempt to
automatically import the SQL files.
Fix the prompt on SDE updater

Yes/no prompt wasn't working, this commit updates it to fix that.
Merge pull request #34 from StephenSwat/dev
