* Replaced push_back calls with emplace_back where applicable.
* Replaced size() == 0 and size() != 0 with empty() and !empty().
* Replaced C style loops for range for loops where applicable.
* Fixed mismatching arg names between function declarations and definitions.
* Replaced NULL and 0 (in the context of pointers) with nullptr.
* Remove unnecessary calls to string::c_str() where applicable.
* Replaced deprecated C headers with proper C++ headers.

(deleting a null pointer has no effect).
* Fixed a potential memory leak in apngloader.cpp file.
* Replaced unsafe strcpy with strncpy in the demangle_name function.
Unfortunately UITextEdit is really bad in terms of performance. It
cannot be used as overlying widget (just like in terminal). On the other
hand we could optimize it by rewriting (unfortunately) the whole widget.
There still is a lot of things to do, but for now it is possible to
select several lines of text and copy it using CTRL + C. In order to
make text copyable in context menu it will be required to override
onMousePress (return true).
