edited advanced search form for spacing

Edited css to reduce spacing in header row (Find records with...).

Brought filter checkboxes to one row.

Removed search button from within advanced search window as the search button outside the window to the top right issues the same action (as well as does hitting enter on the keyboard)

Now able to see the pro tip pop in after a search completes (or if the pro tip has been dismissed) the first row of the record set.
