Feature additional configs (location, prefix, status bar)

Adding several configuration for advanced usage: * **floax-x** and **floax-y** to define floating pane location * floax-status-bar: To toggle status bar * floax-prefix: To define the prefix used for quick actions (*) *) I didn't know that 'M' was 'Alt' in Linux, I thought it was the Option key in MacOs... When I realized it was already implemented :facepalm:
