- decided it made more sense to make a key_get_active function, switched

to that in editmesh as well as for edit{curve,lattice}
 - added a G.editModeTitleExtra string that gets displayed in header info
   string in editmode. currently used to display "(Key)" when editing a
   key (before there was not UI level display of this info).
