Small Quality Of Life gathering

[pipliz]

QoL things that will hopefully be incorporated once adjacent things are touched, or when there's some spare time to fill or such.

• Chat; command completion prompts, for discoverability and such
• Chat; pressing up/down when nothing is typed yet to scroll through previously sent messages (may conflict with completion prompts)
• Chat; proper extendable /help
• Chat; resizable chat
• Chat; modcallback that can intercept chat being sent/received
• Localization; localize keymapping key descriptions
• Day-cycle options. Have the option for { 24/7 day light, regular npc cycle } or { 24/7 day light, only day cycle for npcs }. The 2nd one is more complicated to add, but the first one should be relatively easy. For people who dislike building in the night and such. Add a permanent visual night mode as well for the fun of it.
• Modding; add Middle Mouse Button to the OnPlayerClicked callback. Likely just add a key entry for Primary Action, Secondary Action, Tertiary action, and bind them default to left/right/middle mouse
• Modding; add mouse-down / mouse-up entries for OnPlayerClicked
• Modding; add a player input callback for "mod buttons"; say default F5-F12 "Misc Function 1-7" keys for the keymapping entries
• Modding: Make parts of ModCallbackHandler internals public / expose a RemoveCallback option, for better support for replacing builtin callbacks
• Improve player projectile logic to be able to hit other players
• Stockpile UI fills up all slots, players confused about whether it's "full" since there's no more empty ones
