This patch includes:
* Continue replacing `const char*` with `const std::string&` where it makes sense.
* It also removes some Hungarian notation from the code.
* It fixes some indentation issues in part of the code
* It replaces `int` or `unsigned int` with `long` where it makes sense.
... instead of const char*
* Because it is more robust
* and it is faster... yes faster.
It is faster because internally some of our classes use std::string
(like FileUtils and Dictionary) so converting back-and-forth from const
char * to std::string is very expensive.
It is faster to have everthing in std::string as soon as possible to
prevent further conversions.
There are still some parts of the code that require conversion, but
most of the code was converted.
