Installer uses deprecated MySQL system variable

Core fails to install on recent versions of MySQL such as 5.7.9, because the default JDBC URL uses an invalid system variable 'storage_engine'. The system variable should be renamed to default_storage_engine. See https://talk.openmrs.org/t/mysql-sqlexception-unknown-system-variable-storage-engine-on-install/3905 for more details.

The full stacktrace of the error is:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.
