Drupal conversion

We plan to integrate BOINC's web features with Drupal. BOINC features that have Drupal equivalents will be eliminated, and we'll use Drupal instead. This includes:

• forums
• profiles
• private messages
• friend lists

Other BOINC web features will be packaged as a Drupal "module". These include:

• the BOINC notion of account and login (based on email address and password)
• host features (view, merge)
• team features
• display of BOINC-specific user info (e.g., credit, other projects)
• jobs and credit
• computing preferences

BOINC's web RPCs will continue to exist as they are now.

(This is being implemented by Tristan Olive under the direction of Matt Blumberg).
