New  LX150-EIGHT-B (buggy, see extended descrip)

Separates the pbkdf and salsa clock domains and adds dynamic clock via
DCM_CLKGEN. WARNING the dynamic clock generation is buggy and can lock
up occasionally.
BeMicro port by "Minor"
Updated dynamic clocking

Added a watchdog and minimum clock speed to prevent lockups
Added experimental/ZTEX

Currently just for discussion with vpereira, see the README
More experimental code
Added build instructions
33khash/sec on Lancelot board
33kHash/sec bitstream
Simplified salsa datapath

Salsa I/O now goes via RAM, thus simplifying the data multiplexer at a
small cost in extra clock cycles but it should route better. Also tidied
parameterisation.
Added 64 thread variant
Add Ztex-1-15y
Add 2 core bitstream to Ztex README
Add Cainsmore CM1
Faster bitstream
Support faster bitstreams

Increase freq limit to 300MHz for CM1. Extend scanned nonce range on
ztex to reduce duplicates and allow clock to be locked.
Faster bitstream
Updated ztex README with build notes
Add DE2-115-SLOWSIXTEEN
