Handle exceptions from within phpcq differently
Handle exceptions from within phpcq differently

When a plugin causes a problem in the phpcq application this triggers an
exception derived from `Phpcq\Exception\Exception`.

As all exceptions are now extending the plugin exception
`Phpcq\PluginApi\Version10\RuntimeException` above exceptions were
swallowed and would only be logged with "verbose" verbosity.

We now log these significant exceptions on "normal" verbosity and show
the stack trace on "verbose" verbosity.
