1 - Change QStringList() << a << b << c to QStringList { a, b, c};
2 - Split really long lines in main.cpp
The command line options setup are too big to fit in the screen
this breaks one parameter per line (as a single parameter can
take more than 80 characters sometimes).
Not all of the strings can be read in the line yet, but
this is an improvement.
I'm unsure if the gettext tools will extract correctly the
string if I transform it in a multiline c++ string, so I'm
leaving those as is.
