Check running processes at startup.

Retrieve the processes running at startup and compare with a list of
potentially problematic ones.  Right now this is Itunes which is known to be
able to cause problems when trying to install the bootloader on an Ipod. No
user notification yet.

This adds the implementation for Windows.
