special blocks end lists

It seems that the blocks created by this package cause lists to stop when exporting, as well as generally leaving empty lines after the content in the exported file. Would it be possible to have the blocks remain inside the list?

An example:
``` org
1. builtin block
#+begin_src latex
\uline{does not end lists}
#+end_src
2. org-special-blocks
#+begin_proposition
does not end lists
#+end_proposition
3. org-special-block-extras builtin block
#+begin_stutter 5
this ends lists
#+end_stutter
4. org-special-block-extras custom defblock
#+begin_thm
this ends lists
#+end_thm
```
becomes
```latex
\begin{enumerate}
\item builtin block
\begin{verbatim}
\uline{does not end lists}
\end{verbatim}
\item org-special-blocks
\begin{proposition}
does not end lists
\end{proposition}
\item org-special-block-extras builtin block
\end{enumerate}

this ends lists

this ends lists

this ends lists

this ends lists

this ends lists

\begin{enumerate}
\item org-special-block-extras custom defblock
\end{enumerate}
\begin{theorem}
this ends lists

\end{theorem}
```
and similarly in HTML.
