2014.12.17 MSS Code Factory CFDbTest 2.1.12704 Database connection established from Servlets

The EAR has been removed from the project.  The PostgreSQL-specific WAR has been removed from the
project.

The server configuration is now used to specify CFDbTest21ConnectionPool (which I have bound to
the PostgreSQL driver), and CFDbTest21PoolClass (correspondingly set to
net.sourceforge.msscodefactory.cfdbtest.v2_1.CFDbTestPgSql.CFDbTestPgSqlSchemaPool) and the WAR
carries all of the database-specific variants of JDBC with it instead of having multiple
installations, one per database.

At this point in time, I've got a login page wired to retrieve a backing store instance from
the pool, use it, and return it to the pool.  Along the way, it issues a redirect to a page
that will be used to set the initial system account password before you're allowed to do
anything else.

Realistically, this was the hard part.  The HTML pages and their processing are pretty trivial
compared to getting the stack working.
