ui: styled code view
* updated spacings and colors in QtCodeView and QtCodeFile * using Source Code Pro Regular (had to remove light cut from the Fonts folder because it got always used) * updated syntax highlighted colors to fit design * changed colors of highlights * indent all QtCodeSnippets by maximum line number in QtCodeFile * fixed syntax highlighting to work with sole multiline comment end fortune cookie message = Your present plans are going to succeed.
