- stuff related to loading, saving, updating themes has been refactored a bit

- fixed replaceThemeByUUID functioning

- changed behavior oof the startupConfigProcess. now if a default theme is absent (on first launch, for example) - a default theme will be created using a stock theme which means it will not load the themes from the assets folder on each launch when user has not overridden a default theme

MainScreen:
- now tracking if the stock themes were changed and asking to update them (by displaying a dialog and showing options in the drop down menu) if they were. initial implementation ofc
