* Feature/fileselect (#58)
* Start file select notes
* Blank out file select tileset template
* Preliminary string printing
Had to change the signature of the base
print_chr function because the file select
screen uses a lot of non-standard memory
layouts. For example, the tilemap has a
variable width instead of the standard 32
tiles.
* Include string data in linker script
* Update notes
* Print the full array
* Add external calls
* Add FILE_SELECT struct
* Add format_file_string
* Widen main file select window
* Format full text speed string
* Add build badges to readme
* Oops on the master badge link
* Update README
* Fix file select not showing any info because of wrong palette.
* Make it so before printing the tiles are properly cleared
* Commit for the day. Missing Delete and Copy from File Select menu
* Add Delete and Copy
Also document all windows for future
* Setup basic alphabet - Need cursoring
* Add support for not-multiple-of-8-Ys to print_character_with_callback
* Add support to extra Y tile if and only if it's needed to print_character_with_callback
* Improve cursoring for new Y
* Add summary support
