Added instructions for accessing the pe-postgres user.
Corrected Markdown syntax errors, reorganized Console UI section

* Corrected an instance where an example html tag was not placed in
backticks.
* Reorganized the Console UI Terminology to not only correct Markdown
syntax (some lists were not displaying as lists), but to make the whole
thing into a series of hierarchical lists.
Added version specifics for Solaris (PE-1539)
Set record straight on origin of a bug we fixed in 3.3.1
Update gem source URL to https://rubygems.org/

(The old URLs both redirect there, anyway.)
Update installation guide w/ inconsistent service name on Fedora (DOC-204)
Change mco inventory page to say "inventory" in the sidebar
Abandon "resource stashing" as description for catalog storage/searching

catalog storage and searching have turned out to be not all that confusing.
Delete redundant and dodgy text in guides/exported_resources.markdown

- Stop comparing exported resources to virtual resources, no one really
  considers the similarity relevant.
- In fact, stop describing the syntax/behavior on this page entirely. That's
  what the language reference is for, so link to it.
- Collector overrides have nothing to do w/ exported resources. DELETE.
