Wake-on-LAN functionality

Hey ljunkie

My setup at home involves the use of a Windows PMS server which I auto-sleep to save power.  Previously, I had to use my phone to wake up the server every time i wanted stream my library.  I've been working over the past few days on getting remote wakeup (Wake-on-LAN) functionality to work with the Roku client.  After a few days of experimentation, I've finally got this working to my satisfaction.

I decided to fork your Client instead of official because of all the extra featuers!  I think it'd be great if you included this as part of your next official and development releases.  Feel free to send me an email or catch me at #plex IRC if you have any questions.

Cheers
