Added keyword search + tests. Skipping recordSearch input field when adding records to a space. Removed unnecessary form fields from all forms, since they're already created by the template helpers.
Moved searchForm out of recordForm.scala.html. No need to JS the value of the search input element anymore.
Added tags to users, spaces and circles. Added light-weight getName function to User class.
Circles have the same look as spaces.
Circles get the same look as spaces (to be finished).
