Introduced the INI variable “BOOTDELAY” to set the timeout for the auto boot feature

Is this a new feature where if no button is hit during bootmii, it will automaticlly go to the wii menu? What are the details on this new feature and how do I use it?

This customizes the delay for the AUTOBOOT option. Defaults to 5 sec. It's in the README.

If you look in the bootmii.ini file, the options are already there but just commented out. Just uncomment the option for autoboot and then set the delay to whatever you want, it works great! I was waiting for something like this to install BootMii since I don't usually want to find a gamecube controller just to get to the Wii menu. One thing I noticed is that the little dots for the countdown are always 5 in number, even if you set the delay lower, and then it goes to Wii menu before all the dots are gone (obviously) which is kind of a polish bug I guess, but it's a nice touch overall.
