Started working on new extension framework based on proc files
Added proc files for some window state (in a crappy way for now)
Got read-only proc files implemented pretty well
Got simple write only proc files working
Proc files are now either readable or writeable. Added writeable proc file for the selection.
Redid proc files so that they work better with the file system
Updated help file
Added some loggingf
Tweaked layout
Added a command key for get info
Got invoke working with lua extensions
Handle some lua errors better
Added identifier element
Got the first lua extension working
Also write extension errors to the transcript. Show line number for syntax error.
Write selection-range now scrolls into view and shows the indicator.
Make proc file paths more consistent.
Proc files now assume that the main thread is blocked.
Writing to selection-range now defers the operation.
Added ForceLog option to logging settings.
