tex2lyx: towards beamer overlay argument support.
Implemented: Overlay and standard overlay arguments for commands
and environments.
Still missing:
* List item overlay
* itemcommand overlay (\overprint)
* overlay via LatexParam (e.g., Flex:ArticleMode)
Needs fixing:
* General list argument (\begin{itemize}[arg])
* nested content in a frame with no title (empty par)
(cherry picked from commit 949de66956)
