* exwm-input.el (exwm-input--on-KeyPress-line-mode, exwm-input-prefix-keys): Allow users to disable 'C-c' prefixed keys; Add 'C-c' to / remove 'M-!' from the default prefix keys. * exwm-workspace.el (exwm-workspace--x-create-frame, exwm-workspace--init): Advice `x-create-frame' to prevent it from hanging EXWM, making e.g. speedbar working. * exwm-floating.el (exwm-floating--set-floating): Remove the now unnecessary request that sets override-redirect on floating frames.
