Berthold Stoeger 2cd7b9db25 Warnings: replace memcpy by assignment 
New gcc (v8.2) complains about memcpy()ing an object with non-POD
members. Even though this seems not to be an issue for template_options,
the warning has some merrit. The compiler will recognize when to do
a memcpy() anyway. Moreover, the assignment is easier to read and also
more secure, as a-priory we can't know if Qt's QColor copy-constructor
does some strange things (hopefully not).

Thus, replace memcpy() by simple assignment.
