Showtime Plugin Navi-X

There is in Files section a new zip archive it includes the following changes:

- Old processors version (aka pre-NIPL processors) support: might still need extra work;
- Some processors that failed now should work: Animefreak, Movdivx, Peeje and maybe others;
- Some processor improvements: should support now regular expressions that exist in Python but not in Javascript; In order to get the headers of a page just HEAD it instead of downloading the page, it improves speed;
