EVE-47 - Event formatting should appear in "Profile" window

  EVE-74 - Change in-viewer support for 'notify me' to be maintainable via app slurl
  EVE-72 - Modify viewer to make the event profile window be an html control

This is basically a reworking of the event profile display to remove all in-viewer
specific event display rendering, in preparation for richtext descriptions.
Most was removal of code.
