Slightly rewrote the news ticker architecture

- The news ticker is now a stealth button that opens a window.
- News window now has brandings for FNN and Pawprint Press.
- Ticker now provides extra lore by me if is_caseyverse.txt is present.
- Moved the news ticker functions to the window source, for now.
- Added .gdignore
