Summary: Arbitrary scale rate scaler

Initial Comment:
This patch adds a minimalistic implementation of a scaler that allows for arbitrary scale rates.
The actual rate of scale is set by adding a value for gfx_scale to the configuration file, e.g. gfx_scale=2.3 would scale in a rate of 2.3.

Disabling float-based scaling is enabled by defining the DISABLE_FLOAT_SCALER macro.

The way the scaler is implemented adds some ugly artifacts to moving objects. Also, scaling is done in a trivial way so there is no anti-aliasing as in other scalers. You might want to fix that some time.

I know this is far from being perfect but at least it helped me play ScummVM on my TV :)
