Reason: a long time I wondered how exactly this Code Analysis works and wasn't even aware of that for "cppcheck" .h files are _not_ scanned.
- Rearrange to GUI to make the label better fit (at least for my eye): move selector and start
button from the lower right to the upper left.
IDEAS for later:
- The info label can be reused later when it is possible to run the code analysis for individual files to inform user about this.
- Another analyser which derives from the cppcheck class could be created: it specifically sets the language to C++ (the original class the caption should be renamed to "cppcheck (C/C++) and also includes .h and .hpp files
