Subject: [PATCH] doc: Modernize the container documentation.

This hass the following tags:

 * @interface
 * @tparam
 * @propbeautiful
 * @propemits
 * @renamedin

Beside tags, it adds some comments, fix formatting and add
new lines and dots where they belong.

Also add some signals to standardize everything.
