Moved SetTooltipScripts() and GenericCreateButton() toward the top of the file, just under the frame cache code.
In GenericCreateButton(): Removed the setting of global frame names and removed anchoring parameters - everywhere this function was called now also has a :SetPoint() call for the returned button.
Removed several button:SetText() calls, since the call to GenericCreateButton() directly above them took care of this.
Renamed CreateExpandedPanelcheckButton() to CreateFilterMenuButton().
ARL_FilterButton is now MainPanel.filter_toggle and is created in the main file body instead of addon:InitializeFrame().
