Title: LPS-30847 Refactor Journal Content code for RSS feeds 

This PR includes:

* Definition of the supported RSS feedTypes through a portal property, based on the ROME project specification.
* Renaming of some ambiguous attributes in RSSUtil. Now the concept of feedType is used to refer the same as in ROME project's SyndFeed (i.e. the combination of a feed format, such as "RSS" and a version, such as "1.0"), while the former "type" concept (refering only to the feed format) has been renamed to "format".
* Applying the above described changes to refactor the code for the feed editing in JournalContent. Notice that in JournalFeedService we're using feedType to refer to the feed format ("rss", "atom") and not to the feedType as defined in ROME ("rss_1.0"). The field name has been preserved for back-compatibility but if necessary, it could be modified through an upgrade process.
