UI: About dialog does not actually say what Pinta is about (Painting)

[Alan Horkan]

For users new to Pinta or those who might find it already installed on a computer the About dialog fails to tell you what the program is about, namely "Painting". Most users will probably guess but it should still be clearly explained.

The standard GTK about dialog includes a comment field, where most good applications explain what the application is about. Maybe Pinta could use the standard GtkAbout dialog rather than a custom version.

It does not seem to be possible to copy/cut and paste text from the About dialog. It would make things slightly easier for ordinary users if developers could advise them to quickly and easily cut all the most relevant version information from the about dialog and paste it into a report.
