new function: ::content::revision::export_to_filesystem
This change moves functionality from file-storage to acs-content-repository. all application packages should be free of internals, such as the storage type. Storage_type should be handeled in the content-repository package.
We are not yet done, there is still more to do in this respect in the file-storage package.
Refactoring of the upload-size-limit admin page of the file-storage. Sets a default value of 2GB when no maxinput is found in the config file, and uses the new 'number' ad_form widget. Bump version for the widget dependency
