This reverts commit 6df031dc786256e0bd42f8047d6c308e90abedf6.
I revert this commit for the following reasons:
- MissingParameterException must not be thrown manually because we have UrlParams::getRequired() which was UrlParams::req() before.
- The commit introduces the untranslated string 'host or service'.
- 4xx are client, not server errors.
- Copy and paste code for the stack trace handling in the ErrorController.
refs #6281
Multiline strings are not considered being a valid title. This patch
strips all but the first line from the exception message when setting
the title attribute.
- 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)
refs #4530
This exception should be fired when the OS restricts the web user
from executing certain actions. Also the template for errors has
been modified so it displays the action and the target that
was prevented.
