Decode HTML special characters in post titles

[seanmturley]

Description

Some post titles contain HTML special characters which are not currently being decoded e.g.:

• http://localhost:3000/natureddit/fullpage/r/winterporn/comments/1adzbyw/winter_hills_trees/
• http://localhost:3000/natureddit/fullpage/r/LandscapePhotography/comments/1ae2rz6/some_of_my_photos_from_last_year_iceland_trip/

Approach

It looks like the best approach is to use the DOMParser API (as described on StackOverflow). Importantly, this approach avoids creating a vulnerability to Cross-Site Scripting.

This should now be fixed, though I should keep an eye out for similar issues in other fields beyond the title.
