parse categories, add multiple field values support (for categories)
Fields with multiple values are separated by '|'. In the future multiple enclosure support might be added. The categories tags are now parsed. This feature is useful for filtering and categorizing. Parsing of nested tags such as <author><name> has been improved. This code has been refactored. RSS <guid> isPermaLink is now handled differently also and will now prefer a permalink with "true" (link) over the ID. In practise multiple <guid> in an item does not happen.
