* fix local variable will be copied despite being returned by name
error when building with clang 7
* Fix error return-std-move
std::move should not be used here because
it prevents RVO (copy elision) and it's
considered an anti-pattern.
To fix the original warning the returned
type must match the declared return
type or copy elision will not be possible
(and the warning will be triggered).
* Update ColorScheme.cpp
* Disables automatic conversions from 8-bit strings (char *) to unicode
QStrings.
* Disables automatic conversion from QString to 8-bit strings (char *).
* Disables automatic conversions from QByteArray to const char * or const
void *.
* Disables automatic conversions from QString (or char *) to QUrl.
* Use QStringBuilder for more efficient string creation.
It make us aware of string and encoding conversions.
