#154 Expand Gamma Setting Options

[Anonymous]

On some systems (all of the ones I own, at least, especially the Nokia N810 and Sharp Zaurus SL-C3100), everything is too dark to be fun to play, even on the "Lightest" setting.

I made a small change that allows for the alpha to be set to an "ActuallyLightEnough" setting, or 0.40F, as it is in actual_gamma_values.

I suppose it would possibly be better to put the gamma on a number scale (eg, from 1 (darkest) to 10 (lightest)) instead of the current one as well.

Sorry, I bungled that patch. It should be something like this (sorry if these don't work, but you should get what I did):
