Added back the "!reinforce" sprite, used for medium grabs (it's a shitty gray sprite saying UP-GRADE with a blue X).
If anyone wants to make better sprites for it, go ahead. As for now, it was missing and one type of grab was invisible on your hand.
Resolves #830 - ghost_form is only selectable by members.
ghost_form is now saved with other preferences.
Public visibility of memberships is toggable and saved with other preferences.
ooc-colors for admins and members are now sanitized. Bright colours like Yellow, white and baby-blue will be darkened for the sake of legibility.
Related to above - added helper procs to convert between RGB and HSL colour models.
Admins cannot modify var/unlock_content without +DEBUG rights. unlock_content moved from client into prefs.

Player savefile version number updated - this will trigger savefile updates, no data should be lost.
Merge pull request #835 from Carn/mob_defines

Removed some unused variables in mob definitions:
#821 Incorrect plaque tile gas values

This corrects the commemorative Goon plaque at the Arrivals Shuttle. It previously had the values of gas set low and an approximation of what the values should be. The temperature was also extremely low. This pull sets the values to the default of the other floor tiles.

Arrivals will become cold randomly, but not every round. The epicenter of this coldness is the plaque (thanks to dumpdavid for helping us figure it out). It is a map edited floor tile, it is the exact same as every other tile except it has its values edited on the map.

I am not sure if this will fix arrivals getting cold, but the values of the tile are an anomaly and should be reverted to the default values.

Map-merger died. Had to merge by hand.
