Fixes up a few minor things in README.md

* Properly linked all the Open CAFE and CloudRoast repos, since all
  the links were simply pointing at the full StackForge project list.

* Makes <USER_HOME>, <PRODUCT>, etc. visible when viewing readme
  on GitHub; these were being interpreted as HTML tags before, so
  paths were showing as "/.cloudcafe/logs///statistics", for instance.
  Escaping them as code shows them properly.

* Used consistent line lengths (yielded to the liberal 120 character
  convention due to some of the inline tags and so forth).

* Fixed formatting errors in the configuration section, mostly due to
  the ordered list not appearing rendered as an ordered list the way
  it appeared in plain text.

* Matched package anatomy rendered format to match Open CAFE package
  anatomy format (bulleted).

* Spaced things out consistently for the gentle plain-text reader.
