Base document authorization on directories, not files

Change document authorization to be directory-based (like activity
files) rather than file-based.

Add the Reviews and Reviewers tables to the Place Reviews example tables
in Ramp Demo (the three tables in the extended example in Zend Framework
in Action by Allen, Lo, and Brown are Places, Reviews, and Users
(Reviewers)).

Remove <a name="..."> from README and document files; use id's instead.

Make minor style changes, mostly to the colors used by the Ramp Demo.
Hide user on set/change password screens (broken by Twitter Bootstrap)
Support Markdown in tables and fields
Create separate sequence setting for tabular views

Create new sequence setting (sequence.tabularView) for tabular views, so
that they don't have to use the same setting as single record views.
This is particularly important at the moment because tabular views can
include Markdown in field labels, whereas single record views cannot,
but it may continue to be helpful even once single record views support
Markdown in field labels since a tabular view is, in essence, a report,
and so might include different fields from those included in a single
record view.  Update regression test suite to test new tabular view
functionality.

Update documentation of various Ramp administrative activities,
introducing some skeletal structure to documents that previously had
nothing and polishing those documents that had substantial information.

Make very minor style adjustments.
Update Release # in About files
