soft-rf: Fixing Addrtobuf (converts Number to 8byte-buffer (pseudo-64bit-int))
Soft-rf24: Fake mode and Fixes

Introduced fake mode to soft-rf24: If SPI and GPIO can't be loaded (because the hardware isn't there on non-rpi-machines), load fake modules instead which output data to console for debugging purposes.
Fixes: a lot of this and self issues which could also have been solved by using .bind(this). Also some typos.
