>Description:
ctwm_app_menu takes forever (2.5sec on my laptop, 20sec on wiiu).

This runs whenever you start ctwm or something.

It runs to generate a menu from installed .desktop files.
>How-To-Repeat:
launch ctwm and open the menu
>Fix:
rewrite in awk so it reads each file once, not nine times

 	src/external/mit/ctwm/libexec: ctwm_app_menu

 Log Message:
 ctwm_app_menu: Rewrite largely in awk for ~20-100x speedup.

 Previously took ~2.5sec on my laptop, now 0.03sec.

 Previously took ~10sec on a wiiu, now ~0.5sec.

 Output is meant to be byte-for-byte identical, except possibly in
 cases that could have screwed up ctwm by quoting shenanigans which
 are now escaped.  (I hope the escape sequences work, didn't actually
 check how ctwm interprets them.)  Can maybe support Exec line with
 `"' in them by deleting some code (marked XXX) but I didn't test that
 it actually works that way.
