Fixed various GC failures.
Converted integrated radios (used in PDA cartridges) to Initialize.
Added a missing Destroy to the QM PDA cartridge's integrated radio.
Fixed a runtime when mineturfs with no ore were destroyed by explosions.
Fixed a runtime when explosions attempted to Z-travel.
Minor radio performance improvements.
Converted radio globals to defines.
Changed the Security-I and Medical-I frequencies to use the same colors as their respective departments.
Fixes #2646.
