Mqttk

Added features
- Export selected message content as raw binary data
- Option for exports to only encode message payload into base64 when it can't be exported as a string (contains binary data)
- Option to generate a random client ID at the moment of connecting to the broker, instead of a fixed ID. This allows multiple clients using the same configuration to connect simultaneously without having to manually change the client ID.

Bugfixes
- Fixed a race condition that sometimes caused message IDs to shift and incorrect message content being shown

Added features
- On the log tab there is now an option to enable the debug output message entries of the paho-mqtt client in the log

Bugfixes
- Fixed a glitch that in some cases, caused tab content not to display completely after switching tabs. Shoutout and a big thank you to [raumlandbahnhof](https://github.com/raumlandbahnhof) for his contribution!
- Fixed positioning of the absolutely fantastic splash screen image
- Removed an unnecessary warning log entry that was generated when first selecting a communication profile
- While the log window is open, new entries won't set the unread log entry indicator in the Log tab label
- After selecting a new item in a drop-down, in some cases, the newly selected option was highlighted in the combobox, this should no longer be the case

Additional changes
- When a connection profile is selected in the main window and the Configure button is pressed, the selected profile will be selected upon the opening of the configuration dialog.
- After configuring a connection profile in the configuration dialog and the OK button is pressed, the last edited profile will be selected automatically in the main window
- The log window automatically scrolls to the bottom of its contents upon a new entry
