1.2.0 Adds support for owner label

= start:Belle:

< This message will now be labeled

Will become

{
  "ownerLabel":"Belle",
  "sections":[{ "id":"start", "messages":[{"type":"sent", "name":"Belle", "message":"This message will now be labeled"}], "options":[] }]
}

To get the same result as version 1.1.0, just add .sections to any Compiler.compile() call.
