This addresses an issue reported on the Forum where creating a new FAQ and
not filling out required information returns the correct error but returns
the incorrect template (FAQ View Template). This is due to the check for an
FAQ when determining the template to return. This adds a check for the FAQ
ID to determine if it’s an actual FAQ or just a model instance.

This addresses an issue where FAQ & Canned Response attachments are dropping
when another agent edits the FAQ or Canned Response.

This pass also makes a stride at adding correct punctuation and making error
phrases consistent.

This is my attempt at removing similar texts from the translator work load.
It also makes an attempt at dropping some misspelled words and works toward
standardizing some phrases.
