Check whether upgrading to Crack is part of the materials availability check

[ymitropoulos-01]

It has been noticed that there are cases where a player tried to transfer materials (ind. points) from the warehouse to another entity (merchant ship), and while GUI allowed the action, the engine produced an error.

At the same turn, the player had upgraded units to "Crack Elite". Since this is a rare command, check whether it is part of the availability check.
