Enumerable#compact now removes undefined values
Ensure that all view observers are scheduled

Previously Ember.View#registerObserver did not schedule observers as part of
the 'render' queue. In some cases we implemented an additional 'invoker'
that took care of this but it was not universally applied. Here we move the
scheduling into registerObserver itself. This will help prevent unnecessary
DOM updates.

remove "~YUIDOC_LINE~!" from generated documentation

This happens because YUI does a regex replace to close end of lines with
"~YUIDOC_LINE~!". If you put the description of the parameter on the
next line, you need to have at least one word on the line the parameter
is defined. e.g.:

/**
  @method foo
  @param wait A
    thing I am describing
**/

vs

/**
  @method foo
  @param wait
    A thing I am describing
**/
