Revamp the Blocking Master Example

* Use the 'const' keywords more.
* Split very long lines.
* Use the 'm_' prefixes for all class members.
* Use the QOverload in signal/slot casting.
* Use more member class initializations.
* Remove QT_USE_NAMESPACE macro.
* Use from(to)Utf8 instead of from(to)Local8Bit.
