ISO Loader 0.8.x Beta + preview of DreamShell v4.0 RC 5

[SWAT]

New test build: https://github.com/DC-SWAT/DreamShell/re...0.0RC5-T37

I managed to save few extra bytes of memory by changing the version string from "beta.37" to "RC.1"
And I succeeded because... I fixed most of data transfer issues!!!
All WinCE works perfectly now, also some KATANA like MSR, prototypes and so on. All these games loading faster and without issues for me.
Also fixed DMA with IRQ in some games like Expendable and 4 Wheel Thunder, now these games works good with true async DMA and IRQ.
But some games still doesn't like IRQ due to out of stack I guess. MSR doesn't like it.

There is some changes for UI fade effects and console show/hide.
Also I changed scrolling method by joystick for FileManager widget. It doesn't work super stable, but I think it will be more common this way.
