[chimerax-users] Removing text labels generated with command distance

[Tom Goddard]

I made a ChimeraX fix so labels will not cause problems in no gui mode.  I put this in the daily builds (and eventually in ChimeraX 1.5), but not in the ChimeraX 1.4 release candidate since we are too close to releasing 1.4 to include it.
