Files with "+" character in file name are not rendered

[jri]

When clicking a File topic the underlying file (e.g. an image) is not rendered in the detail panel if the file name contains a "+" character. Apparently in the request the file name is not properly URL-encoded.

Fix: files with "+" in path are rendered (#819).

A file whose path contains a "+" character is properly rendered in the detail panel.

BREAKING CHANGES

A file repository path contained in a /files/ or /filerepo/ request must be encoded as a URI component, e.g. with Javascript's encodeURIComponent function. In particular the "+" character must be encoded ("%2B"). (The encodeURI function would not work.)

Plugins that use the Files plugin's client-side open_upload_dialog(upload_url, callback) utility method are responsible for encoding the passed URL.

When using a reverse proxy it must be configured to NOT perform any URL decoding before passing the request to the application.

See #819.
