Fixed the First Aid display by altering the number of lines to display in the FauxScrollFrame if the number of entries is less then NUM_RECIPE_LINES.

ARL_ProgressBar is now MainPanel.progress_bar - yay for not polluting the global namespace!
SetProgressBar() is now MainPanel:UpdateProgressBar()
Renamed MainPanel:ResetTitle() to MainPanel:UpdateTitle()
Re-worked ARL_ClassButton's OnClick script to iteratively toggle class filters rather than doing them individually, and replaced a call to UnitClass("player") with Player["Class"].
Moved assignment of MainPanel to addon.Frame from addon:InitializeFrame() to the file body.
