Bug Fixes - v0.6.0.30

Just a couple of fixes for the weekend. The main one being a really bizarre issue, that caused the whole screen to go white during play! This happened when a captured meteor would pass directly over a tractor beam, and the fx i was using didn't like a very small value. Looks like an engine issue, but for the time being, i've just made sure i don't pass small numbers in!

Thanks to Cornellus for the bug report and save file/info. ːsteamthumbsupː
