Extended and fixed Pelican theme tuxlite_tbs and tuxlite_tbs
============================================
    
become compatible with Pelican 3.2 and 3.3 documentation: http://docs.getpelican.com/en/latest/settings.html  to get the feed links working with with  FEED_ATOM and FEED_RSS (which now default to "None") but also FEED_ALL_ATOM and FEED_ALL_RSS.
    
enable firefox to dynamic-bookmark the feeds by adding meta data.

Extended Pelican theme bootstrap
=========================
   
For  firefox dynamic-bookmark the metadata were only aware of FEED_ALL_ATOM and FEED_ALL_RSS, but the docs  http://docs.getpelican.com/en/latest/settings.html also name FEED_ATOM and FEED_RSS. So I added awareness for them.
    
Since the Theme did not show any menu-link for the feeds, I did NOT add them.

I could work me through the rest of the themes and check if I can add this issues. 
If I should do so, please send me a note.
