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

[SWAT]

Additional info about loader type and low memory value max for each:

Default/Base - 0x8c004800 max (without any features except CSO)
Extended - 0x8c004000 max (CDDA and IRQ only)
Full - 0x8c001100 max (all features)

Any loader can be placed in any high memory of course.
If used Extended with CDDA/IRQ at 0x8c000100 then Heap placed in low memory too. If used CDDA without IRQ then heap placed in high memory at 0x8cfe0000. The full loader always placed Heap at high memory if used CDDA, no matter with IRQ or not.
