Adds drawing to tacmaps (#4475)

# About the pull request
Features 
- Gives cic (sos, xo, co) and the queen the ability to draw on the
tactical map and then announce it to their respective factions
- All marine faction members now are able to access the tactical map
announcement through the stat panel, which can be viewed at any time.
- Xenos in addition to having the normal tactical map will also have
access to their own canvas map that can be viewed when Queen is on ovi.
- Ghosts can view the tactical maps for both factions in the Ghost tab
as well as from ghost alert popups.
- Admins can view all the round's drawings and optionally delete them.
# Explain why it's good for the game
Hopefully this will spice things up for cic, queen and players alike.
The idea is command and the queen would now be able to better convey
what they want from their faction, which should help with general
cohesion and likely expand strategic plays on both sides. (don't abuse
it or harry will take it away, or make it more exclusive to the queen
and co)
