Berthold Stoeger 50b11024d6 core: keep tank infos in a dynamic table
The list of known tank types were kept in a fixed size table.
Instead, use a dynamic table with our horrendous table macros.
This is more flexible and sensible.

While doing this, clean up the TankInfoModel, which was leaking
memory.
