logic: Moved all error handling logic into ErrorController (issue #577)

* Handle all error related messages in ErrorController
* Moved error filter state from Storage to ErrorController
* Moved all error related messages to type/error subdirectory
* Enable all errors shown by default
* Always show unfiltered error count in status bar and overview
* Fixed all errors shown again when changing error filter on errors for file
