* Added the ability to type the partial name of a region in the start location box and go to that region if it's there. If no close match was found, it sends you home. This is tested on mySQL. There's untested code on grids that are based on sqlite and MSSQL. The SQL statements *should* be right, but your results may very.

* Ex, if you want to go to Wright Plaza, you simply need to type Wright Plaza in the start location in the client when you log-in.
