Feature: Player ID pages

FUNCTIONALITY: 
This adds in individual pages of the type `nfl/players/:espn_id`

From the player list page, a link to link to the individual players page also exists. 
Currently this is a base implementation, as the individual players page template is simply a re-rendering of the list player template. 

STYLE:
-Also removed bullet list styling
TODO: Will add a more fleshed out player id page in the future.
