Added multiple liquibase.properties command line commands

Added multiple update, rollback, documentation and maintenance commands.
All requiring the liquibase.properties file.

- for the updateSQL command i created a new target\liquibase\sql\ folder
with file script.sql. This will store generated SQL after running it.
- for the dbDoc command i created a new target\liquibase\dbDoc\ folder.
This will store a generated html website containing all information
about the current state of the database.
