Added ability to change overlay alphas independently and renderstyles.

Browse source 
- A_OverlayRenderStyle(int layer, int style) - Sets the renderstyle of a layer to one of the STYLE_ types.
- A_OverlayAlpha(int layer, float alphaset) - Sets the alpha of a layer.
- OverlayAlpha(int layer) - Non-action function retrieves the alpha of a layer.

New overlay flags:

- PSPF_ALPHA/STYLE - enables individual alpha and render styles on the layers set with them.
- PSPF_FORCE(ALPHA/STYLE) - Forces the overlay's alpha to be rendered with its own amount instead of multiplying. This does not count towards fuzzy, transsouls, or stencil (use stenciladd, etc. for stencil).
- PSPF_FLIP - Flips the X of the layer over, drawing it in reverse.
