7aeae40af2 EXPERIMENTAL: A new way of setting intensity; introducing xintensity! 
All of this is credited to ArGee of RGMiner, he did the initial ground work for this setting.

This new setting allows for a much finer grained intensity setting and also opens up for dual gpu threads on devices not previously able to. Note: make sure to use lower thread-concurrency values when you increase cpu threads.

Intensity is currently used to spawn GPU threads as a simple 2^value setting.
  I:13 =    8192 threads
  I:15 =   32768 threads
  I:17 =  131072 threads
  I:18 =  262144 threads
  I:19 =  524288 threads
  I:20 = 1048576 threads
Notice how the higher settings increase thread count tremendously.

Now enter the xintensity setting (Yes, I am a genius with my naming convention!).
It is simply a shader multiplier, obviously based on the amount of shaders you got on a card, this should allow the same value to scale with different card models.
   6970 with 1536 shaders: xI:64 = 98304 threads
R9 280X with 2048 shaders: xI:64 = 131072 threads
 R9 290 with 2560 shaders: xI:64 = 180224 threads
R9 290X with 2816 shaders: xI:64 = 163840 threads

   6970 with 1536 shaders: xI:300 = 460800 threads
R9 280X with 2048 shaders: xI:300 = 614400 threads
 R9 290 with 2560 shaders: xI:300 = 768000 threads
R9 290X with 2816 shaders: xI:300 = 844800 threads

It's now much easier to control thread intensity and it potentially allows for a uniform way of setting the intensity on your system. I'm very interested in constructive feedback, as I do not have access to a lot of different card models.

This change has been tested on 6970, R9 290, R9 290X - all with equal or a little better speeds than regular intensity setting after a little tuning, but your mileage may vary. Don't fret it, if this doesn't work for you, the regular intensity setting is still available.

d0070c0424 HARD RESET to: Remove Bitcoin detection code. 
I'm pretty sure no one was working on this but me.

The code was unusable (gave 100% hardware errors) due to me not
testing it sufficiently. I hope this will not happen again.

ADL doesn't work for some reason, too.

69983b778b Revert "Pick worksize 256 with Cypress if none is specified." 
This reverts commit 482322a4b7.

Worksize 256 was only helpful on cypress with ultra-low memory speeds with old SDKs and the new kernels require higher memory clocks, having the opposite net effect.
