(Patch by KrossX): Fixed multitap - Part 2 - (e.g. Timesplitters), New: support raw PSX

memcards (mcd/mcr), Fixed issues with pad 2 (e.g. issue 1326).

These are changes which were left out at r5622, updated to pach v9 by KrossX from http://forums.pcsx2.net/Thread-Multitap-PCSX2 .

- Please report any issues with memcards corruption/incompatibilities here.
- Please feedback on multitap improvements here.

Thanks, KrossX! :)
