Fixed issues pointed out by Reijo.

The number of threads is now atleast 1.
Added a very simple about dialog with version number and license.
Replaced all CppCheck's with Cppcheck.
Renamed "show more errors" to "show possible false positives" in the menu.
User created application now has to have a name and a path.
