#1196 Error List doesn't clear w/mult. views

[Derek Groothuis]

Another multiple view issue - this one's actually been
around for a while but I kept forgetting to report it.
When compiling (at least in Java), and using the Error
List, if you have multiple views and are compiling , it
sometimes starts to get confused and keeps old errors.
Essentially, errors from older compilations hang
around, and the only way to clear them is to exit jEdit
and restart it.

It might be nice to have a Clear All Error command, that
could be triggered on demand.

The console maintains an independent error source for each view.
