Add possibility to set volume to more than 100%
Created by: jle64
Would you consider adding the possibility to set volume to more than the current limit ? This can be useful for example on laptops with low-powered speakers.
This pull-request adds the possibility to set volume up to 150% and also adds a label indicating the volume level so that it's obvious when it's set to more than 100%.
The value of 150% is abitrary (it's approximately what you can set with pavucontrol), I also made a version in which the max value of the slider can be set through preferences but this seemed a bit too much, although I could make a pull request with it if you prefer.
Anyway thanks for your time and for sharing this extension.
