The Arquillian configuration for MySQL tests was wrong, as it was
using the H2 data type factory instead of MySQL's. This commit fixes
this error and now tests with MySQL should work fine.

The project dependencies have been updated, including a change from
WildFly 8.2.1 to 10.1.0. This change affects the project configuration
in several ways, specially in tests configuration.

The README.md file has been updated to reflect the configuration
changes.
