RTEMS/Emulator Wiki page.

[Karel Gardas]

Hello,

I've added top-level `Running RTEMS in the emulator' wiki page plus some 
content to it. Please feel free to share your knowledge of running
RTEMS on top of any emulators there.

Please also feel free to fix any typo/mistake which might went there, as 
I'm not native English speaker.

Thanks!
Karel
