Fedora Workstation PRD draft 3

Hi everyone, Ok, wanted to send out a quick update which includes all the sentence/spelling fixes people sent. I also tried clarifying the integrated desktop experience item as Lukáš Tinkl suggested. Only thing I haven't done here is reworked the goals listing as per Ryan's suggestion as it would be a bigger job and I am not convinced the end result would produce a 'better' text. That said I am open to suggestions if someone wants to propose and alternate text/layout to this section. Christian
