#1358 Add support for LaTeX lstlisting environment

[Neil Hodgson]

From Hugues Larrive:

Portion of non-latex code in lstlisting environment can break syntax
highlighting.

As exemple the '$' in:

\begin{lstlisting}[language=make]
# If no BOARD is found in the environment, use this default:
BOARD ?= bluepill

# To use chinese st-link v2 and ch340 dongle with bluepill
ifeq ($(BOARD),bluepill)
STLINK_VERSION=2
PORT_LINUX=/dev/ttyUSB0
endif
\end{lstlisting}

I think the lstlisting environment should be treated as the verbatim
environment and I did the following modification to do so :
