BUG #14198: Making it easier to add new annotations.

Users can now add/edit annotations easily. Simply add the first row using the
"+" button and double click to start editing the text. Now by hitting Tab key,
one can edit the next item in the table. By hitting Tab key past the last item,
one can add new rows to the list as well.

BUG #14187. Fix default to not cache animations.

ParaView by default caches animation geometry. With cached geomtry the
data-ranges cannot be shown correctly. Since geometry-caching happens under the
covers it difficult for users to understand what's going on with data-ranges.
Hence, we change the default to not cache. Thus when users do turn on
geometry-caching, they can be made away that that will affect data ranges.
