Update beams.dm

Bumps laser cannon damage back up to double a laser.  Anything between 51-99 basically has the same function anyway, and bigger numbers are just nicer.  Pulse still crits in two and can tear through walls, so I don't think it's a problem.  And both are outdone by the sniper rifle, because stuns, crits in two, effortlessly orderable from cargo at round-start.  I like to think cannons are meant for use against xenos, rogue mechs, wizards, etc and not usually normal humans.  -Duck
