Fixed enter so it's stable again.
Made minor tweaks for compatibility between wxGTK and wxMSW
Fixed roomview so that 'skip' shows up again in button bar
Still working on windoze images.  They're only showing half-height.
Fixed wholist so that it fires up maximized.  Fixed the button problems
in 'wholist' under wxMSW.
REfixed roomtree.cpp so that under wxMSW it is clickable again.
Certain things here are for tests.  DoChat was one of them.  This is not
yet a release version of the software, LS, so please don't give me crap
about things I'm testing.
