Changelog for version 4.2

Shmupmame 4.2 changelog:

Critical Fixes:
-Fixed major direct 3d bugs/problems.

Input delay related improvements:
New method for removing input lag that does not affect the emulation accuracy and can remove an additional frame of lag:
-Namco Sytem 1 has one less frame of input delay (some games 2, apparently) in addition to the older buffer fix.
-Most games Namco Sytem 2 have one less frame of input delay (excluding some of the racing games)
-Psikyo old hardware (psikyo.c) games have one less frame of input delay in addition to the older buffer fix.
-Mars matrix has one less frame of input delay

Game specific improvements/additions:
-Added autosword button in Marx Matris (like in the dreamcast version), mapped to button 2
-Added sound support using samples for Same Same Same, Fire Shark, Vimana, Ghox
and Teki Paki (Thanks to thundermame for the code and to BPzeBanshee for renaming the mame v143 functions to v148)

General Additions:
-Added “cleanratio” option which finds the largest integer scaling for the current view and then sets the correct aspect ratio
-Added “Viewpercent” option which determines which percentage of the screen will be used for drawing the game, can be used in combination with cleanratio or alone
to specify an exact view size (range is floating point 0-1, 1 being 100%).
-Added autofire settings saving for individual games
-Added autofire rate display in Hertz in addition to “delays”
-Added functionality for different autofire rates for main buttons and custom buttons
-Added a few more artwork types (scanlines every 4 lines)

Minor Fixes:
-Brought back 1945kiii and G-stream g2020 which were mistakenly removed in Shmupmame 4
