GridUserService in place. Replaces the contrived concept of storing user's home and position info in the presence service. WARNING: I violated a taboo by deleting 2 migration files and simplifying the original table creation for Presence. This should not cause any problems to anyone, though. Things will work with the new simplified table, as well as with the previous contrived one. If there are any problems, solving them is as easy as dropping the presence table and deleting its row in the migrations table. The presence info only exists during a user's session anyway.
BTW, the Meshing files want to be committed too -- EOFs.
