We have not been good at consistent casing so far. Now we use 'Sentence case' everywhere. EVERYWHERE.
Also Removing 'Lc' prefix from i18n field names: the 'Lc' stood for lowercase but now that everything
is in 'Sentence case' there's no need for the distinction.
I've got a couple lower case things I've kept: namely, things that show up in parentheses.
The reason for this is that now our labels for navigation keybindings are larger so they
take up more realestate. It's not the kind of thing a user needs to be told anyway,
anybody is going to try out hjkl and the arrow keys when a TUI opens up.
We could map from <up> to the single character up unicode rune but given you can rebind this stuff
I'd rather keep it simple
This begins a big refactor of moving more code out of the Gui struct into contexts, controllers, and helpers. We also move some code into structs in the
gui package purely for the sake of better encapsulation
