wip - changes from last time I worked on this

Switch to a fullscreen layout with side-by-side frames

Add flag for debug logging

Add GPLv3 license

Initial commit

Description, date, and total fields are functional. Next step is to
start adding structure to the form and adding a window to the side which
will show previous similar transactions and autocomplete suggestions.
Arrow keys will be able to auto-fill the current field from the selected
suggestion.
