Fix "r_ignorehwgamma 1" and support for "r_ignorehwgamma -1"

Due to poor support for hardware SDL gamma (see http://bugzilla.libsdl.org/show_bug.cgi?id=971 ), software gamma is important, but currently there is no way to actually turn s/w gamma on if SDL pretends to support h/w.

Currently, r_ignorehwgamma 1 just turns off calls to GLimp_SetGamma() without resetting glConfig.deviceSupportsGamma to zero, which results in dim output.

Fixed by a simple patch that also adds support for forcing hardware gamma via "r_ignorehwgamma -1".
