TempDB Resizing/Reconfig is broken

[AirborneGeek]

In its current form, it resizes the existing file to whatever the max size for the DB is supposed to be.

I've got a fix for this written, but I'm going to piggyback some other changes to the TempDB area with it.

Removed TempDB Max Size to address bug. Will debate on best practice for max file size--current will just fill up volume, which I think is ok for tempdb. Unless we come up with a smart calc for volume size based on TempDB and number of files. Testing now.
