Added 2 new hooks for view options form: hook_views_rss_options_form_validate() and hook_views_rss_options_form_submit()

Renamed theme functions and template files: "views_view_views_rss_fields" to "views_view_views_rss" and "views_rss_fields_item" to "views_view_views_rss_fields", updated template suggestions for "views_view_views_rss_fields"

Added 4 new hooks and modified old ones, added data caching, added install files, changed view options array structure, moved files and functions around, fixed #1426930, docs, code cleaning

Added "RSS email: with user name" format for email fields, fixed empty <guid> element showing even if not defined

Initial version of 7.x-2.x branch, during a major rewrite. Definitely not finished yet, most of the main features should already work fine though.
