Break out LLMakeOutfitDialog.

Added "Make Outfit..." to Edit menu and Create->"New Outfit" to inventory floater menu.
Cleaned up LLMakeOutfitDialog, using boost::bind and less waste.
Moved onMakeOutfitCommit() to LLMakeOutfitDialog as makeOutfit()
Also changes LLFloaterCustomize's callbacks to use boost::bind
Give new outfit dialog a title instead of a heading.

Small fix to mistake with AnnounceSnapshots xmlstuffs.
