Minor update 3

Noticed mistake in last update so rushed to make quick update. Also there seemed to be some weird cursor issues with very large screens. I try to come up with something for next update.

• Fixed reinforcements not sometimes appearing when curse mod was active (forgot to round up timer number)
• Fixed parrot sometimes sleeping
• Fixed some arena bosses not moving during arena (when player was in other side of the room)
• Fixed bomber/helicopter launcher & ufo launcher ammo cost. Ammo cost now properly scales with clipsize. Base ammo cost reduced from 50 to 40
• Vampyrusman no longer deals collision damage
• Some other small fixes
