The error displayed on screen was already improved (see #280)
This commit improves the log message we can have for example by running unattended install.
The setup now relies on the new method MissingDependencyException::getHtmlDesc to get the message to display
MissingDependencyException is also now a CoreException child.
Note that previous behavior (MissingDependencyException instantiator setting message) is kept, as some consumer still do $e->getMessage() (like unattended install)
