- We now have both minPlasma* and maxPlasma* variables.
- *PlasmaRate now goes from 1 to 5 just like Damage and Output.
- Internally, plasma now goes into the primary weapon, there is no
temporary weapon anymore.
- When upgrading the primary weapon, the new minimum amount of Damage,
Output and Rate immediately goes into effect when starting the next
msision.
- Super Charge now works exactly the same again as in the original.
- But shows blinkenlights in the bottom status bar when it is in use.
There were three flags, WF_STRAIGHT, WF_THIN_SPREAD and WF_WIDE_SPREAD,
when only one flag, WF_SPREAD suffices. This makes the code simpler and
gets rid of some duplication.
