Add handlebars helper for pluralization
- Takes n and a thing string as inputs
- If n is one, then no pluralization is needed
- If n is greater than one, then the thing string will be pluralized
Use pluralize function along with handlebars in postItem html
- Now will show count and pluralized word if more than one vote
- Will also do the same for the comments handlebars helper
