- Rename ConfigurationController to ConfigController
- ConfigController and PreferenceController are now subclasses of
BaseConfigController and BasePreferenceController
- Module and Application Config/Preference Tabs are detected via
the ControllerTabCollector
- Moved Controller classes to Icinga/Web/Controller (this is why
so many files are modified)

The constructor of the class is now private, instantiation happens
with Url::fromRequest and Url::fromPath. Also updated all occurences
of Url and fixed the Qlink helper to not overwrite the baseUrl with null
values
