Added headers to table, something's not working

Ok, so I added the <thead> tag to the table so we could get our column headers,
went to try and do ngclick things in our links and whatnot, realized that the
damn thing wasn't settling ($digest >= 10, blah blah blah) undid all the changes,
still going apeshit.
Added the 'current' object to DatabaseApp.js

added an object to track the values in the current relation. (side effect #1:
the dropdown links update!)
