PCSX2: Presets: 1. GUI consistency. 2. Fine tuned presets.
The presets system is hopefully done, code wise. Fine-tunning the presets
themselves may still take place.

- GUI behavior should be as follows:
1. Overall: any changes made to the GUI without clicking Apply or OK would be
discarded (on ESC or Cancel or close ([X])).
2. On 'Presets' unchecked: As long as the config dialog is open, the GUI
stays with the values of the current preset (alternative behavior is
available with #define PRESETS_USE_APPLIED_CONFIG_ON_UNCHECK).

--> NOTE: OK/Cancel/Apply buttons are never disabled. This is also true for
r3768. Needs fixing one day.

- Fine tuned presets with some help from rama and pseudonim. Current Presets
are as follows (each preset adds to the previous one):

1 - Safest : Default settings + Individual speed hacks unticked (to make it
visually clearer they're not used).
2 - Safe (faster) : Recommended speed hacks minus vuFlagHack.
3 - Balanced : enable vuFlagHack, enable EE timing hack, EE cycle rate to 1
click.
4 - Aggressive : VU cycle steal to 1 click, enable (m)vuBlockHack, VU clamp
mode to 'none'.
5 - Aggressive plus : EE cycle rate to 2 clicks (maximum).
6 - Mostly Harmful : VU cycle steal to 2 clicks (maximum-1).

Note: The GUI consistency stuff turned out harder than I thought. I
intentionally left in the code some commented out Console.WriteLN calls which
should help debugging in case it's needed, but they should be removed
eventually. I'd appreciate some regression tests and possibly code review for
the entire presets system. Thanks.

Presets GUI consistency fix: Speedhacks 'Restore Defaults' resulted in
grayed-out controls if last applied settings include presets enabled.
