Fixed issues arising from merge.  

-Secured /services/* behind a filter which attempts to access BASIC
authorization tables "users" and "authorities" in a DB called test.  DB
can be configured via webSecurityConfig.xml.

-Removed residual Spring tutorial files.

NOTE: The version Peggy had most recently pushed to master did not
include code for connecting to an actual database.  Its currently using
UserMockRepositoryImpl.java to fake a user DB (which is seperate from
the DB used for user authentication)
