Adding Tags to a Post

[matthojo]

• commas are now getting included in tags
• suggestion/typeahead menu should close when a tag is deleted
  • this currently works when deleting tags by pressing [backspace], but breaks when deleting tags by clicking on them
• suggestion menu should always be limited to 5 items
• when populating a tag by selecting suggestion and pressing [enter] - suggestion menu should close
