#670 Upgrade values aren't set properly.

[Anonymous]

How to reproduce:
Start VS with vanilla config, dock, look at Weapons - they have bogus statistics affecting lots of irrelevant fields.Look at overdrive parameters - they set a lot of fields to "-100%" too. Fields that should be affected are set to wrong values.
Now set "physics" to "realistic" in setup. Look at Overdrives - now that they cannot overcome "-100%", they have negative effects, slowing the ship down. Installing one affects ship info and actual gameplay as calculated, rather than as it should.

Also, should mult_ -type upgrade's own parameters be adjusted with game_speed at all?

Arr, forgot to login. Also, change "svn" tag to "CSV", please?

Anyway, my suspect is extra initialization from [r13629] - it seems to be indiscriminate.
