Implement last character details screen. Also, rip out built-in dialog support for a library that makes consistent material look across platforms.

CharacterNames now also contains the graphic icon for the character. Implemented character icons and chat depicting game players. Lots of cleanup on UI for spacing. Clearer page names.

Do a better job at fully removing things when deleted. Add more edge case logic. Clean up messy functions. Have players and characters able to be added. Stole an icon from AOSP. ;)

I somehow missed that all similar class objects are stored in the same db. This means I needed to add a more unique id. Renamed classes to make easier to read. Fix typo in spelling. Fill out initial header and UI for character details.
