Updated spring-security-mvc-persisted

Updated spring-security-mvc-persisted - added login error message if
unknown user, and switched default H2 database to be embedded
in-memory. Added explicit sql creation script to automatically create
table on deployment (for some reason the createTableOnStartup flag in
the jdbcTokenRepository didn’t work with embedded H2)
