#1442 Option for Scaling Screen Without Filters

[AntumDeluge]

For retro style 2d games, I often prefer a pixel look as opposed to the blur artifacts of scaling filters. I think it would be a good option to be able to disable scaling filters in the client display.

Edit: I'm assuming the client uses scaling filters. I could be wrong.

When scaled, the java client uses bilinear scaling. It would be possible to use nearest neighbour as well, but I suspect the result would look bad unless the size is an exact integer multiple of the original. (There's no such things as not using a filter when scaling - it's just a choise of the filter used).

Anyway, this can be tested by changing RenderingHints.VALUE_INTERPOLATION_BILINEAR to RenderingHints.VALUE_INTERPOLATION_NEAREST_NEIGHBOR in GameScreen.java. I can't remember if I actually tried it back when scaling was implemented.
