The hotkey widget has a separate class defined for it, and qt cannot automatically retranslate it when retranslateUi is called. This commit explicitly calls the function to retranslate the hotkey dialog.
Corrects a few issues with regards to Doxygen documentation, for example:
- Incorrect parameter referencing.
- Missing @param tags.
- Typos in @param tags.
and a few minor other issues.
