Joey Parrish 6c85c8cbfc fix: Fix rendering of TTML nested cues and spacers ...

TTML nested cues are meant to be displayed horizontally as inline
elements.  This fixes the rendering of these nested cues in both
SimpleTextDisplayer and UITextDisplayer.

In UITextDisplayer, the styles have been adjusted to lay out the
nested cues horizontally rather than vertically.

In SimpleTextDisplayer, the nested cues were being displayed as if
they were top-level cues.  This change concatenates the nested cues
into a single cue displayed in the browser.

This also improves comments on the poorly-named "spacer" property,
which represents a line break in TTML.

This fixes the rendering of "spacer" in SimpleTextDisplayer by
inserting an actual newline character into the collapsed nested cues.

Finally, this fixes and clarifies names used internally in
UITextDisplayer.  For example, there is a difference between a nested
cue and leaf cue.  A nested cue and a top-level cue without nested
cues are both "leaf" cues, but a top-level cue is never a "nested"
cue, since it is at the top level.  The conflation of these names
before this fix made it difficult to understand and fix the code in
the first place.

Closes #2760
