began ESPN::NFL spice

mostly ripped from NBA, but all seems well. perhaps time to revisit
shared code/styles in spice. could make the tabbed ZCI into a new
template but I don't think it'd be worth the effort.
began ESPN::NHL (see 5885c6 for comments)
Minor changes to Forecast styling, especially on mobile.
News: Find out if we trimmed inside a bold tag.

Close it if we did:
>>> ddg_spice_news.ellipsis("US President Barack <b>Obama said</b> Tuesday.", 40)
"US President Barack <b>Obama said</b> ..."
>>> ddg_spice_news.ellipsis("US President Barack <b>Obama said</b> Tuesday.", 35)
"US President Barack <b>Obama</b> ..."
News: Changed the ellipsis function.

It's simpler to just count the number of open and closing tags. If there is a mismatch (we cut between two tags), then we just append a closing tag.
