refactor: better ability handling

[NotSugden]

This PR aims to better the handling for the role ability buttons

Full list of changes:

• Ability buttons now enable/disable with the HUD (eg, when opening the map the button is hidden, before the button would stay active)
• Whenever a target is selected for a role's ability, the target gets an outline the same color as the role, so a Sheriff has a yellow target outline
• Ability buttons cooldown only goes down while the player is not in a menu (same as impostor cooldown)
  • However, it still goes down with a task open, I have had feedback about this change and the majority prefer roles like sheriff to not have a reason to not do their tasks
• Fixes any existing issues with the Altruist revive
• Better vote handling
  • This also fixes the issue with all clients seeing a tie instead of a skip
• If the Time Lord walks up to vitals, with the time lord can use vitals setting off, the use button doesn't highlight (previously the vitals screen would open and close immiedietly)
• Removed FixLights RPC call in favour of the EngineerFix RPC call
• Removed ExecutionerToJester RPC call in favour of a local PlayerControl.Die patch
• Changed the internals of how the Shifter works
  • No longer needs to be updated it more Impostor roles are added (lol)
• Morphling and Glitch morph/mimic abilities are now disabled if camo is active
• The hack ability no longer breaks a shield
• The Glitch's Mimic menu now has an exit button (#176)
• Refactored the internals of the hack ability (#250)
• The Miner can no longer place vents in under the map positions
  • The miner vents can be placed in un-usable positions, but
• Janitor, Undertaker and Altruist can no longer be used through walls
• The check and X mark when voting now slide in for the mayor
• Adds new Button Barry button sprite (provided by @dumbplayer2)
• Fixed the mayor vote buttons not sliding in
• Updated to 2021.6.30
• Removes skip vote text from mayor abstain button
• Removes kill text on all ability buttons

NEW BUGS INTRODUCED BY 2.2.0 FIXED BY THIS PR:

• Swapper can actually get button barry (see here)
• The correct kill sprite is used for sheriff/glitch kill buttons
• The glitch can now have button barry, but the button is moved

Status: PR is ready, may need some tweaking but other than that its ready

~~PR is ready~~, just needs some more testing before being merged, no doubt with a PR this size theres probably an issue i didn't come across while making

on second thoughts, converting back to a draft for the moment

[NotSugden]

converting to draft as more issue(s) need to be addressed
