-Add TextureManager support for linear 320x200 raw page lumps.
-Fix line breaking for menu notification messages. Also print them using doom_font.
-Remove usage of patch_t in d_main.cpp, am_map.cpp and m_menu.cpp.

-Slightly optimize the loops in the 32bpp DCanvas::Dim functions.
-Blit at the beginning of each row until the destination address is 16-byte aligned. This allows the use of aligned SSE2 intrinsics rather than the slower unaligned ones. Hopefully this results in a speed increase when the console is lowered or when displaying a color overlay effect such as item pickup flash or red pain flash.

-Use SSE2 intrinsics for calculating the (u, v) coordinates when rendering a span.

-Rewrite the blend4vs1_sse2 macro as a set of instructions inline in r_dimpatchD_SSE2 for better readability.
