2023-01-12Add an indicator to the status bar when in insert modecflip
2023-01-12Make the editor modal and refactor keyboard eventscflip
This makes the editor behave more like vi, with a seperate insert mode. This also refactors the keyboard input code to pass the SDL_Keysym structure to input.c and to use the SDL_TEXTINPUT event for editing text. SDL's text input event already fixes typing capital letters with shift, and should make it possible to enter text using an IME, however most unicode characters aren't properly rendered.

2023-01-11Get editor size from the window instead of the terminalcflip
Previously the editor would resize itself upon startup by finding the size of the current terminal window, but now that it is running in an actual window it should get the number of rows and columns from there. This also adds parameters for the window size in rows and columns to the window_init() function.
