Fixes #130

Fixes #149

via PR #134 @looer

Added config variable so this doesn't show up

Show "reading time" and "word count" but only if one of the following are true:
1) A global config `params` value is set `show_reading_time = true`
 2) A section front matter value is set `show_reading_time = true`
3) A page front matter value is set `show_reading_time = true`

Fixes #115
