linhes-scripts: idle.sh: Check if frontends are playing. closes #851.

Add -d option that will include mythshutdown daily wake in system busy calculation. Default excludes daily wake in system busy calculation. This is needed to use idle.sh as the PreCheck for system shutdown.

Add -w option to check for open windows. Before checking for windows was default but in some cases the user won't want the check. Adding window check as an option makes it consistant with the login check.
