Summary: [gemlist] may output invalid GemState

Initial Comment:
when triggering a [gemlist] out of context (e.g. by connecting it to [gemmouse]) it might output an invalid (though once-valid) state, triggering a crash (when accessing the image in the state)

this only happened when directly triggering from [gemmouse], not by manually clicking on a bang and not by triggering it from [gemhead].
[gemmouse] should be recent enough.

see attached patch

Message:
hopefully fixed with rev2871 (by copying the content of GemState rather
than the pointer to it in [gemlist])

LATER: make a refcounter for shared objects

Message:
to add more info:
Pd/Gem  won't crash if the [gemmouse] event is delayed (e.g. only 0 ms)
however, handling of mouse-events should already be re-queued (i'm using
gem-0.92.svn), so i don't understand this.

btw, i'm on Debian/linux running kernel-2.6.18 and xorg-7.3 (X Server
1.4.2)
