HDMI monitor settings

I've noticed If I plug my HDMI tv in after the pi is already booted I get no video at all without a reboot. (Also, we might want to experiment with the yellow composite output to see if we get video there too)

There are some /boot/config.txt options that might be of interest to us:

hdmi_force_hotplug=1 Use HDMI mode even if no HDMI monitor is detected hdmi_drive=2 Normal HDMI mode (Sound will be sent if supported and enabled)

update:

this works and allows me to plug in my HDMI tv at anytime, but the audio is then forced to the headphone jack and is not automatic. I suppose it's best not to use hdmi_force_hotplug so that we can support composite video out, but I don't see an issue with adding hdmi_drive=2.

I'll try to test this with my old CRT TV on the next release.
