Erstes großes Refactoring

* alle gemeinsamen Funktionen in includes/galleryfunctions.php
   zusammengeführt (fixes #21)
 * AJAX-Requests werden in ajaxrequest.php behandelt und liefern
   zusätzlich zum Titel auch die URLs des Vorschau- und des Vollbildes
   (fixes #22), die übergebenen Request-Parameter werden syntaktisch
   geprüft (fixes #23)
 * Die Vorschau- und Thumbnail-Bilder werden in der Funktion
   getScaledImage() in includes/galleryfunctions.php generiert und im
   Filesystem abgelegt (fixes #10)
 * Bildbeschreibungen sind jetzt in einem .ini-Format in
   bilder/example/galleryinfo.ini in der Sektion "images" definiert
   (addresses #20)
 * Rendern der Menüpunkte in index.php und
   includes/galleryfunctions.php vorbereitet (addresses #16)
 * Die AJAX-Aufrufe und Pfadberechnungen in scripts/ourhandlers.js
   wurden korrigiert und an die neue AJAX-Handler-URL angepasst
   (addresses #22, fixes #19)
 * Beispielbilder in Unterverzeichnis ''bilder/example'' verschoben
   und die Möglichkeit vorgesehen in ''bilder/galleryinfo.ini'' eine
   Standardgallerie anzugeben (fixes #24, addresses #20, #16)
