Adaptive Database

As part of the VPN project, phase one (agreed by the HCMC Committee), I've enhanced the Adaptive DB codebase with a couple of new features:

• You can now search for a comma-separated list of integers in an integer field (so you can retrieve a specific known set of records by their ids, for instance).
• Input from the search form is much better sanitized than before.
• The search wildcard character has been switched from the SQL % to the more familiar asterisk (*), and backslash-escaping of the wildcard now allows you to search for it as a literal character.
• Help pages and popup help buttons have been enhanced.

This development was done on the VPN dev db, and will be rolled out to the live version for full testing, before being rolled out to other dbs.
