Issue #121 packaging, debianstyle (pull request attempt 2)

(Redoing this pull request because I f'd up the other one.)

How to build the .debs:
wget https://github.com/Nuand/bladeRF/archive/master.tar.gz
tar -zxvf master.tar.gz
cd bladeRF-master
debuild -i -us -uc -b

Caveat: once we get into a groove release-wise, we'll need to remember
to update debian/changelog (look at the 'dch' command)

This produces three .deb files:
bladerf_0~20131005-2_amd64.deb
Contains bladeRF-cli, bladeRF-flash, and man pages
libbladerf0_0~20131005-2_amd64.deb
Contains libbladeRF.so.0
libbladerf0-dev_0~20131005-2_amd64.deb
Contains libbladeRF.so symlink, libbladeRF.h, and libbladeRF.pc

This is still somewhat fragile. Also, it pretty much depends on
Ubuntu 13.10, which hasn't been released yet. But we're ahead of
the game, no?!
