[Beta] Debian/Ubuntu builds for Ppcoin and Peerunity

This is almost ready as is, I am calling it beta only as not enough people have installed it so far.

For Debian 8.0 run the following as root:
Add keys first:

wget http://download.opensuse.org/repositories/home:peerchemist/Debian_8.0/Release.key apt-key add - < Release.key

echo 'deb http://download.opensuse.org/repositories/home:/peerchemist/Debian_8.0/ /' >> /etc/apt/sources.list.d/ppcoin.list apt-get update apt-get install peerunity

For Ubuntu 15.10 run following as regular user:

keys first:

wget http://download.opensuse.org/repositories/home:peerchemist/xUbuntu_15.10/Release.key sudo apt-key add - < Release.key

sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:/peerchemist/xUbuntu_15.10/ /' >> /etc/apt/sources.list.d/ppcoin.list" sudo apt-get update sudo apt-get install peerunity
