Feature - Implemented Prevent use of Potion of the Field Gar on Mondays

[Fred Nefler]

Since the field gar effect has no benefits when the server's day of the week is Monday (it's fine before 12:00 am Monday kol server time, and after 12:00am Tuesday, for example), it might be nice if mafia prevented or warned about using the field gar potion at this time. Possibly even warn about eating lasagnas on Monday when the effect is already present?

Preventing the use of field gar on Mondays is done with the attached patch, with some code borrowed from Tuesday's Ruby. Warnings seem harder to implement.

 

[Veracity]

Right idea, but wrong format for the message. The "limiter" is used to plug into the error message: "(usable quantity of xxx is limited to Y by <limiter>)". So, rather than limiter being "That is useless today", it should be something like "uselessness on Mondays" - which is what I did.
