- Introduced hyphenationEnabled flag in ParsedText and Section classes.
- Updated constructors and methods to handle hyphenation settings.
- Modified settings file versioning to include hyphenationEnabled.
- Enhanced settings UI to allow toggling of hyphenation feature.
## Summary
* This PR drastically reshapes the structure of the codebase, moving
from the concept of "Screens" to "Activities", restructing the files and
setting up the concept of subactivities.
* This should help with keep the main file clean and containing all
functional logic in the relevant activity.
* CrossPointState is now also a global singleton which should help with
accessing it from within activities.
## Additional Context
* This is probably going to be a bit disruptive for people with open
PRs, sorry 😞
