This commits adds new "Open XML" item to File-menu. Selecting this
menuitem allows user to select report file to open. When the file is
read the error data is printed to debug output. Later patches will
implement adding error data back to the GUI.
CSV files are handy (and commonly used) to export/import data to other programs. CSV reports allow easy import of cppcheck error data to other programs for further processing.
Include guard naming fix (names starting with underscore+capital letter are reserved in C++, so we should not use those)
