Allow "Local Gravity" To Accept Decimals

A minor issue to be sure, but I was wondering if the "Local Gravity" field for a Fall could allow decimals instead of just whole numbers. I think a lot of 'hard sci-fi' games probably have a lot more locales with gravities of 1.3, 1.8 than they do 3 or 5.

Also, without decimals there is kind of a "dead zone" between zero-gravity and 1g/Earth normal (that is, you can't input any gravity less than 1g).
