A. make, cmake and config parameters. 
This means that we have 2 new options: 
WITH_EMU to enable/disable the (dummy) emu reader, and 
WITH_SOFTCAM to enable/disable linking of softcam.key inside the binary. 
The WITH_SOFTCAM option can be removed completely if you like. 
No code that reads keys is included.

B. All webif changes are included. 
This means that when building WITH_EMU enabled, 
there will be a stream relay page and 
an emu reader "config bit" in the reader settings. 
There will also be a softcam.key link 
to open the softcam.key file and see its content 
(similar to what is done in constant.cw file).

C. When building with disabled WITH_EMU, 
there will be no sign of emu reader anywhere.
