add render_description method to RSSItemView to improve modularity.
The construction of the description marker of and rss entry is currently built
by the main cell_call function. This make the job hard for RSSItemView subclass
to change the default behaviour. The changeset fix this issue by extracting the
description creation into a render_description method. Such extraction are
already in place for various rss marquer.
