Station Table Design

Here's a pass at the full station table design, as discussed by Igor Terekhov, Rich Wellner and Matt Vranicar. There are items for comment and discussion by the SAM Team in here before these can be implemented.

New Tables Needed

Station_Disks

Station_Disk_Statuses

Disk_File_Locations

This could be thought of as Disk File Cache too, but its similar our earlier Data_File_Locations, so I recommend naming it thus. Others can argue and win without much fight from me on this issue. While it is similar in concept to our current Data_File_Locations table, it is different enough to warrant its own table. In light of this, we should really think of our data_file_locations as tape_file_locations - but PLEASE NO NAME CHANGES NOW! Make a synonym if you want! Actually, if we make this split it may make it possible for us to cleanup the implementation of data_file_locations - but let's defer it till after v1.5 shall we?

Disk_File_Project_Deliveries (or a better name if you have one)
