Inline gadgets are missing the "Advanced Search" link for filter/project searching

As well as the auto-complete in the "Quick Find" field for gadgets (Pie Chart, Filter Results, etc.), the old-style gadgets had an Advanced Search link that would pop up a window with more useful search options. The inline gadgets are missing that, and as a result of JRA-32218 this means that filters with certain names are impossible to select for use in the gadget.

ohernandez@atlassian.com suggested a short-term workaround to be adding the Advanced Search option back into inline gadgets.
