Made numerous corrections suggestion by Saivann Carignan (thanks!),
including:
* Replaced GUI autostart instructions with using Bitcoin Core GUI's own
autostart option.
* Described minimum upload speed requirements.
* Described metered bandwidth requirements. Also added a warning about
exceeding periodic bandwidth limits.
* List items that ended with complete sentences (subject+predicate)
received terminal punctuation. Did not terminally punctuate sentence
fragments (sentences missing a subject or predicate).
Also suggested by Saivann, I added an extended section describing
setting up port forwarding on home routers and opening firewall ports to
allow inbound connections to port 8333.
Add basic page with some general information plus instructions for
Ubuntu 14.10.
Change a link on the participate page to point to the full node page.
This page is being added as English-only for now. I figure we can
convert it into a translation template after we have instructions for
Windows and Mac OS X, and after the instrutions have actually been
tested with the released version of Bitcoin Core 0.10.0. (These Ubuntu
instructions were tested with RC3 and the old Ubuntu packaging.)
