Metacat

Added OAI-PMH chapter that was contributed by Duane Costa from LTER.

Fixed formatting.

Moving Metacat Sphinx RST documentation from docs/dev to docs/user directory.

Merged most recent changes from trunk into the RST converted version of the Administrator's Guide. Now the Sphinx/RST version is up to date rlative to the most recent word document, and is now the active copy. The MS Word document will be deprecated and removed. All future changes should be made to the RST version.

Converted the metacat-properties chapter to RST format. Still need to merge in
newer changes from the trunk, as I was accidentally working from the 1.9.4
branch for this whole conversion process.

Removing unused screenshots that are duplicates of the others in the admin doc.

Converted Harvester chapter to RST.

Added stub documents for chapters on DataONE and OAI-PMH (to be converted from
Duane's Word doc).

Small word choice change.

Improved formatting for index.
