Cleanup for release - Githubissues

In this PR I did the following:

Renamed parameterised to parameterized, to be consistent with the documentation;
Removed some unused libraries
Added all JDBC drivers for dbs that Mendix uses to provide a "batteries included" experience when users download the module from the appstore
Add a pom.xml file to manage those drivers (and existing public database-connector dependencies not used only for testing)
Add a script that updates those jdbc drivers as well as package a file containing dependency license information
