seeded random

Browse Source 
all runs are now seeded
seed defaults to the last 8 digits of UTC time in milliseconds
set a custom randomization seed in settings
seed controls:
    at start - boss list, mob type list, level list, horizontal flip
    during run - tech, gun, field choices, some custom level randomization
doesn't control: mob spawns, mob size, some minor level differences, specific level boss choices, ammo reward values, specific tech effects
