Improve notes commands

[FlameArrow57]

[PLAYER ACTIONS][QoL]

About the PR

Improves some things about the notes commands players can use in the Commands tab

-Renames
"Add Note" -> "Notes - Modify"
"Notes" -> "Notes - View"
so that they appear next to each other rather than in different spots (since names are sorted alphabetically)

-Improves Add Note command so that instead of only being able to add individual notes one at a time, your notes are just stored in a single string, changed through a big text box, and can be added/removed

-Uses TGUI prompts for the commands now so that "Notes - Modify" uses a tgui_input_text and "Notes - View" uses a tgui_message

Why's this needed?

Changelog

(u)FlameArrow57
(+)Renamed notes commands in the Commands tab to "Add Note" -> "Notes - Modify" and "Notes" -> "Notes - View". "Notes - Modify" now allows you to add/remove notes all at once, rather than just adding one note at a time.

I'd rather these be combined into a single verb/ui.

Though that is scope creep and these are better than the current ones
