mlanthaler: Add support for _manifest_exclude files (http://support.silverstripe.com/gsoc/ticket/36).
Now it is possible to exclude directories from their inclusion by the ManifestBuilder? by simply adding a "_manifest_exclude" file. This file can be placed in any directory and then that directory and all its subdirectories won't be included anymore. ischommer: merged with current ManifestBuilder, lots of differences (merged from branches/gsoc) git-svn-id: svn://svn.silverstripe.com/silverstripe/open/modules/sapphire/trunk@41950 467b73ca-7a2a-4603-9d3b-597d59a354a9
