Fix file browser issue with parent directory selection (reported by reyalp).
Change to run Lua scripts using a simple 'loader' script - this allows the the source script code to be discarded after the script is parsed saving memory.
Move the 'default' script code to a script file instead of being built into the core CHDK code.
Consolidate the two menu options controlling saved script parameters to a single line in the menu.
Add a menu option to reset the script to the default file.
Remove option to reset script to default (not needed as user can select script file in file browser).
Remove old default.bas script (empty file).
Update changelog.
