Workflows documentation

[Emma Jane Hogbin]

Hello,

I've just updated the Wiki page for the Workflows to include links to
the relevant section of the User Guide. For the most part I was matching
the documentation based on the images in the two documents. Could
someone please check that I've:
(1) linked to the best spot, and
(2) add links for:
	* Decentralized with automatic gatekeeper
	* Decentralized with human gatekeeper
	* Centralized with local commits

The workflows page is at:
http://bazaar-vcs.org/Workflows

Thanks!!


regards,
emma
