Allow WebGoat to create per-user databases

Browse Source 
This creates the infrastructure to allow WebGoat to create per-user
databases, so that any modifications made by one user do not affect
other users. Some lessons may have made provision for this internally
(e.g. CrossSiteScripting lesson), but this simplifies things generally.

This also switches the default database from Access on windows, and
Enhydra on Unix/other platforms to using HSQLDB, in an "in-memory"
configuration. We may get performance problems from having too many
instances of the database in memory at once at sites that have 10's
of users banging on a central WebGoat. Only time will tell.
