21107	[Patch] Some of the key listeners forgot to remove themselves	rickmastfan67	team	"This is similar to #10233 from 2014.

Tested this with my normal and a fresh profile and was able to duplicate it in both.

Steps to reproduce:
1) Once JOSM is started, download a small area of data (doesn't matter how big).
2) Close JOSM.

What happens:
The following errors show up after JOSM closes the RemoteControl connections in the command line.

I manually typed out the errors due to only being able to snag them via a screenshot (which I can add later if requested).
{{{
WARNING: Some of the key listeners forgot to remove themselves: [org.openstreetmap.josm.actions.mapmode.SelectAction@606899f0]
WARNING: Some of the key modifier listeners forgot to remove themselves: org.openstreetmap.josm.tools.ListenerList@57b834ee
}}}

Errors only show up if you download data.  If you start and then close JOSM right away, the issues don't show up.

Also, did some testing to find the regression window.  This was introduced between r17977 (no issue) & r17992 (issue shows up).
