Make RAM disk support work on x86 as well (it is now generic):

Browse source 
1) Don't assert if loaded from setup. On NT this means special things, but we don't care about that for now.
	2) Add to txtsetup.sif along with the other core FS drivers. This will eventually allow installing from ramdisk as well (and later, over the network)
	3) Add to hivesys_i386.inf so that the driver is initialized.

RAM disk now works flawlessly on x86 -- just make sure to follow the previous instructions, and add <size of your RAM disk> to your total memory available to ReactOS.
