owncloud ubuntu linux sync

Since owncloud selective sync only got in after 1.7.0 version of the client i was searching how to use it right away.
But Ubuntu 14.04 ships with owncloud 1.6.2, therefore we need to go around and hack some packages to be able to use this before it reaches ubuntu stable repos:

First install the 1.6.2 client:

sudo apt-get install owncloud-client
