Add hall resources.
Should be defined within hall.json as "hallresources"
Hall resources act exactly the same as normal resources, except their count is tied to the hall. Thus, if a wizard spends a hall resource, that resource is spent for everyone involved. The reverse should also be true - if a wizards adds to a hall resource, everyone can see it.
If a hall resource has a "mod" effect, the "mod" applies to the currently active wizards.
Hall resources only count .rate from hall upgrades and anything on the currently active wizard. Inactive wizards do not contribute.
Hall resources should be visible from the hall interface in player tab, with a separate window opened by "resources" button.
