As part of making lazygit more discoverable, there are certain keys which you almost certainly
need to press when you're in a given mode e.g. 'v' to paste commits when cherry-picking. This
commit prominently shows these keybinding suggestions alongside the others in the option view.
I'm using the same colours for these keybindings as is associated with the mode elsewhere e.g.
yellow for rebasing and cyan for cherry-picking. The cherry-picking one is a bit weird because
we also use cyan text to show loaders and app status at the bottom left so it may be confusing,
but I haven't personally found it awkward from having tested it out myself.
Previously we would render these options whenever a new context was activated, but now that we
need to re-render options whenever a mode changes, I'm instead rendering them on each screen
re-render (i.e. in the layout function). Given how cheap it is to render this text, I think
it's fine performance-wise.
We want to show an error when the user tries to invoke an action that expects only
a single item to be selected.
We're using the GetDisabledReason field to enforce this (as well as DisabledReason
on menu items).
I've created a ListControllerTrait to store some shared convenience functions for this.
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.
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
