#428 group issues

• missing group options i.e loot
• no message when promoting a leader
• leader is not enforced
• /g doesn't send text to group, have to use /gsay (think client related?)
• group portraits doesnt seem to work
• server doesnt let you know that a person has joined your party

RE: /g doesn't send text to group is because someone made a 'gender' command

I am going to remove it from the code and we need to query this to the DB

delete from commands where command='gender';

part of cd17261b83

• promoting leader message added
• group invite accept now notifies the group if player joins
• leader enforcement in certain areas that were lacking (not sure if there is something specific in mind)

outstanding:

• missing group options i.e loot
• group portraits (meh?)

group options for next stage #504 group portraits #505
