removal of lyx-1.4.x, xforms version, and change pkgsrc directories

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

(Long ago, I updated lyx-qt to use LyX 1.5, but then I later saw a 
separate lyx15 directory later.)

The xforms frontend is not longer maintained by LyX.

I'd like to remove the pkgsrc/editors/lyx-xforms and 
pkgsrc/editors/lyx-qt directories.

Then import pkgsrc/editors/lyx for 1.6.x.

Later remove lyx15 if not used.

Any comments? Anyone need lyx-xforms or lyx-1.4 or lyx-1.5?

I can do this after the freeze. (Unless I am told this should be done 
now.)
