filefield 6.x-3.4

This release of FileField fixes an XSS security hole and fixes permission handling in several areas. On the feature side of things, FileField now includes a more flexible API for better integration with 3rd party modules like IMCE and FileField Sources. FileField Meta now stores and exposes ID3 tags (Artist, Album, etc.) through Views and Token support.

New Features:
#480754: filefield_meta: store audio metadata from getid3
#736354: Use module_invoke_all() to check file references in filefield_widget_validate().

Bug Fixes:
#651394: filefield_file_download() is too restrictive when nodes share files
#696906: filefield_edit_access() and filefield_view_access() should use content_access() instead of checking content_permissions specific
#819852: Case sensitive query in filefield_file_download
