/**
 * Add a wordcount counter to the mission post box with a friendly

 * If no limit is defined, the code will fall back to having no limit

 *
 * NOTE: This does not actually limit users in anything; the 'limit' is simply
 * a way to show a note to the user encouraging them to split the post to parts.
 *
 * INSTALLATION:
 * In order to set a word limit, please add these setting keys to user-defined
 * settings in Nova:
 * * 'logcountLimit' (Numerical) The number of words to limit. 0 for no limit.
 * * 'logcountLimitMessage' (String) The message to display in case the post goes
 * above the limit.

Hi I'm having problem with this code:

1. Can't get it to display on mission post/ personal logs
2. Every time I try to add the message variable it cause the site to crash and go white screen, is it meant to go in the nova controller?
