The error section of the automatic, per-job email was systematically empty, even in case of real errors. The Huygens output file was not being properly parsed in this regard. Error messages were missing from the HRM parsing mechanism.
Added 'send test email' function

This allows the administrator to check that the HRM and the underlying
email server are properly set up to send emails to users.
Cosmetic change.

Corrected test e-mail message.
Changed the way the user communicates whether a dataset is 2D or a time series.
Fixes in the (dynamic) help text relating to the special values for z step and time interval.
Changed the order in which the information is sorted in the error notification e-mail. Hopefully improved the code of the corresponding function as well.
Accidentally removed a call to "createScript" in the "notifyError" function when the email text was rearranged. It should not be necessary to re-create the Huygens script (batch template nowadays) when sending an error notification. This should be improved in future versions.
Added  "Process details" at the end of the error notification.
Yet another change in the error notification. Just remove some vertical space.
Bug fix in the check of the Z Step and Time Interval values.
A couple missing characters in a pattern prevented us from parsing some of the restoration parameters properly in the corresponding summary table. Fixed although the pattern became incredibly complicated. TODO: break it down into several, smaller patterns.
Several fixes to the QueueManager in particular when jobs are killed.
Removed a number of obsolete functions.
(1) A few style changes. (2) Added fclose to a function that used fopen without closing the resource later on.

TODO: This class needs a major clean-up.
Fixed broken killing/removing jobs from the queue.
Cleaned spurious characters in Database.inc.php.
Bug fix in the check of the return value of strpos() in Shell.inc.php.
(1) Added support for the new Zeiss file format (czi). (2) Increased the database revision to '11'.
Removed weird characters which were automatically introduced by an editor and which yield PHP warnings.
