puNES v0.84 Changelog

Added an option to pause the emulator when it is in the background. Added the mapper 31 (2A03 Puritans Album http://rainwarrior.ca/projects/nes/2a03puritans.html). In the windows version fixed a bug that did not allow proper recognition of the keys with some keyboard layouts. Thanks to rom test "scanline.nes" I have corrected a timing issue between the CPU and PPU making it even more accurate, while with the test rom "dpcmletterbox.nes" I found and corrected an error in the management of the color pallete. If someone were to find some rom that worked with previous releases and with this not, please contact me.
