CompositeImage.py:
- string.Template to use prefix substitution in ExpandPrefix methos.
${dir} is substituted in any strings
TreeBuilder.py:
- The main control object takes care of updating the hdr_config_panel
instead of expanders. Expander.handleClick method might not be needed
anymore.
Further cleanup of handleClick methods: the main control object is not
passed anymore so Expander objects do not mess with it anymore. Only
Expander specific actions can be executed by handleClick
parent_window parameter is removed from getPopupMenu method of
expanders-
If threaded command is being executed at closing the main window
exception is raised. 'print' added after the mainloop.
