(Patch by KrossX): Fixed multitap (e.g. Timesplitters), New: support raw PSX memcards (mcd/mcr), Fixed issues with pad 2 (e.g. issue 1326).

- Also, I slightly modified the default column widths at the memory card config panel.
- Tip: If the column widths are resized, the new widths will get saved after clicking OK/Apply, but NOT if clicking Cancel or closing the window with [X].
