Genre weapon scaling

Just as sort of an observation. If you never use the genre tech then just
ignore this post right off.

It seems to me that, with the introduction of the Phalons' plasma bolts, the
nova cannon and wave gun (even if you _do_ allow them) seem downright
obsolete. The main messes are that you can't aim it, you can't use any other
weapons at the same time, and you can't scale it up on larger ships (which
aggravates the lack of use of other weapons).

So my thought of late was to allow "classes" of nova/wave guns.  The
version in the FB1 is, under this terminology, a "Class 1" version of those
weapons. Just as with plasma, you can scale up to high classes by putting
multiples of that mass value of the weapon together. A Class 2 nova cannon
does twice as much as a Class 1, etc. Wave guns would charge all the same way,
but the damage that would be inflicted to the ship if a partially charged wave
gun went down in a needle or a threshold would be equal to the amount of the
partial charge times the class of the weapon.

Haven't playtested it at all, but it seems like it might be half worth looking
at.
