GSDX: made the paletted texture handling in the cache a bit more sensible to my eyes and implemented interpolation of palette entries for pixels in paletted textures when using the 8 bit textures option. Regressions in some games I think, such as Virtual On (which is very broken anyway), need to investigate what made them work (to some degree) before. Seems to change some performance characteristics favourably to my surprise, but I might just be bad at remembering framerates.
