Export from Live Script into LaTeX Improvement

The improvement concerns the modification of the matlab.sty file that is created during export phase.

Live Script document is possible to export into several formats (PDF, Word, HTML, LaTeX). Actually the form of automatic LaTeX export does not match the Matlab-language syntax highlighting, and it does not solve problems by special characters displaying (e.g. special letters or symbols in comments or in text strings).
The improvement is in modification of matlab.sty:
- adding required package matlab-prettifier (package in LaTeX distributions)
- changing lst-style into Matlab-editor
- adding special characters in lstset from following link:

In matlabINF.sty there are special Czech characters support, but it is possible to use the same technique for supporting other languages as well (see the link above).
