Guild Loot Limit for Gold

- The command 'guildlootlimitg X Y' has been added to set the limit on how much gold guild members can take per Aberoth day.

- Much like the other guildlootlimit commands, X is the rank and Y is the number of gold pieces they are allowed to take from the guild. 'unlimited' is allowed for Y.

- The defaults for all ranks for all guilds have been set to 0.
