New reports module in GUI

Shortly after queries appeared in ShadowTrackr it was possible to make your own reports with them. These appeared next to the existing, built-in reports and the GUI has been somewhat inconsistent. Some reports could be send, others not. Some results where available as PDF, others not.

With this weeks refactor of the reports module, that is fixed :-) There is also a report library now with reports you can use. You can use them as is, or take them as example and adapt them to your own needs. If you want a specific report that is not there, please let me know. I might be able to make it and add it to the library.
