Patch that makes terminator act like xterm for modified F1-F4.
Terminfo is not affected, since we don't claim anything.
Note: gnome-terminal and konsole still get it wrong, but that's not our problem.
Also adds support for the meta key as a modifier for all special keys.
Note: apply this patch -p1, or go to the directory with no -p#, since I'm not working with the svn diff.
This patch is not affected by my other patch, since it only edits one line of the file involved in this patch (although if you apply this one first, applying the big one will have a simple offset of -13 lines).
