[Qgis-developer] install instructions

[Alex Mandel]

FYI, there's a recently new ppa purge command which is awesome for
cleaning out ppas and stuff they installed back to base system.

As for this issue, I reread some stuff and saw a hint from Victor that
there's a checkbox in the plugin config to enable SAGA 2.0.8 to work
with QGIS 2+

I think SAGA 2.1 will have to wait for newer than Ubuntu 12.04

Thanks,
Alex
