Split single series menu into category submenus

* series menu comes after category menu
* same list but filtered on selected category
Extend categories list

Now using all top-level categories, except alphabetical indexes & abc1/2/3/4
(not just those tagged as genres)

A possible extension to this might be to include the sub-categories.

eg. drama -> all / crime / scifi / etc
Remove unused code path

* get_series_info
* parse_series_info
* parse_series
Remove unused get_meta from parse_series_items
Better sorting for series lists

* case insensitive
* ignores leading 'the'
Use api?keyword=XXX rather than api?seriesIndex

* this api call gives us only the shows we want, and
* gives the full json info (like api?series does)
Add thumbnail & description to series info

We get these now using the api?keyword=XXX call, so may as well use them.
