[IMP] mail, *: template rendering with abstract thread, adapt thread instantiation, thread `getMessages`/`fetchMessages`, and create mode document thread.

* = im_livechat, im_support

- thread widget now uses abstract thread in `render` method
- thread models have their `init` parameters changed, so that the parent may be optional
- reworked 'creating a new record...' in chatter in create mode:
    > new model CreateModeDocumentThread, which basically is a fake document thread
      with a fake message for its rendering in create mode of the chatter
    > special rendering method of thread_widget for such case: `renderChatterCreateMode`
- renamed thread methods previously named `getMessages` to `fetchMessages`:
    > in order to not conflict with `getMessages`, used for rendering
    > now, `getMessages` always get messages that are locally,
      while `fetchMessages` may fetch messages.

TODO:
    - special thread model for im_livechat (rendering is broken ATM)
