Rename generated tags

Tags are by default generated from the class name. But you might want a more user friendly name for your documentation.

This example demonstrate how to strip the suffix Controller at the end of each tag, and then add a space between each word delimided by an uppercase.

For example, the class AdminPanelController.java will then translate to a tag named Admin Panel.
