beamer theorem syntax not fully supported #57
Description
The beamer syntax \begin{theorem}<overlay spec>[heading] is not supported by thmtools while the alternative syntax \begin{theorem}[heading]<overlay spec> is.
\documentclass{beamer}
\setbeamertemplate{theorems}[numbered]
\usepackage{thmtools}
\declaretheorem{MyTheorem}
\begin{document}
\begin{frame}
\begin{MyTheorem}[name=bla]
first text
\end{MyTheorem}
\begin{MyTheorem}<2->[name=bla]
second text
\end{MyTheorem}
\begin{MyTheorem}[name=bla]<3->
third text
\end{MyTheorem}
\end{frame}
% Compare:
\begin{frame}
\begin{theorem}[bla]
first text
\end{theorem}
\begin{theorem}<2->[bla]
second text
\end{theorem}
\begin{theorem}[bla]<3->
third text
\end{theorem}
\end{frame}
\end{document}It's confusing to me that the heading/options are silently ignored in the <2->[name=bla] example, which makes me think that thmtools' intention is to support this syntax, but something is going awry in the code. I haven't spent the time to understand parseargs so I can't debug the definition of \thmt@parsetheoremargs at the moment.
