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.

Updated MetaStation v28M.dmm to MetaStation v28M-II-L.dmm
Database related fixes:
- Fixes the following SQL error:
[13:44:09]GAME: SQL ERROR during death reporting. Error : [Table 'ss13.death' doesn't exist]
The issue was with cyborg death logging, which was not updated properly to log into the correct table.
- Fixed the SQL schema so it properly logs deaths and the legacy_population thing (which logs how many admins and players were on every 5 minutes). If you already have a database set up and don't want to completely wipe it (Let's be honest, you really don't want to do that), look at this thread for help in updating the database properly: http://www.ss13.eu/phpbb/viewtopic.php?f=6&t=194
