(svn r10622) -Feature: Introduction of the CBID_INDUSTRY_AVAILABLE's handling, in fund industry window.
In order to stay as much consistent with the specs, the fund window will perform (if required) the callback every game-day. TTDPatch performs the same call every second, but after discussions with Csaboka, we agreed that it was not required to be that intensive. So a game-day is plenty enough.
