Enabled automated doc building. Changes:

-build.xml, phing build file
-@package tags at acl_selector.php and db_update.php
-added documentation and some IDE files to .gitignore
-automated tool to find files that corrupt the doc build process
-removed ansi characters from SSH1.php, docBlox could not handle them

+ * When I installed docblox, I had the experience that it does not generate any output at all.
+ * This script may be used to find that kind of problems with the documentation build process.
+ * If docblox generates output, use another approach for debugging.
+ *
+ * Basically, docblox takes a list of files to build documentation from. This script assumes there is a file or set of files
+ * breaking the build when it is included in that list. It tries to calculate the smallest list containing these files.
+ * Unfortunatly, the original problem is NP-complete, so what the script does is a best guess only.
+ *
+ * So it starts with a list of all files in the project.
+ * If that list can't be build, it cuts it in two parts and tries both parts independently. If only one of them breaks,
+ * it takes that one and tries the same independently. If both break, it assumes this is the smallest set. This assumption
+ * is not necessarily true. Maybe the smallest set consists of two files and both of them were in different parts when
+ * the list was divided, but by now it is my best guess. To make this assumption better, the list is shuffled after every step. 
+ *
+ * After that, the script tries to remove a file from the list. It tests if the list breaks and if so, it
+ * assumes that the file it removed belongs to the set of errorneous files. 
+ * This is done for all files, so, in the end removing one file leads to a working doc build.
