Parenthesis instead of square brackets

[lellid]

\lbrack and \rbrack are rendered to left and right parentheses (), but they should be rendered to left and right square brackets [].

Moreover, the parser parses a left parenthesis ( to a SymbolAtom containing the name lbrack. I guess the error above arises from the confusion about what lbrack and rbrack are.

Fixed it! I could write a PDR, but I have different VS2017 settings, and its only a few lines in 4 different files, so please have a look at this commit.

Let me know if this is fixing it!
