Scene browse button now works.
Note that animsys currently executes animation for the entire
database, so multiple scenes in multiple windows don't work yet.

Various fixes:

- crash on invoking filewindow when mouse outside (active) window
- removed obsolete error prints (set screen error, copy data error)
- displist fix for loading files with curve/nurbs, the select-outline
  then didnt draw immediately.
- outliner allows scene activating
