Implement Windows Intel driver versioning scheme

[ghost]

These drivers use two component versioning scheme:

driverVersion = (major << 14) | minor;

This change implementts this in getDriverVerson function.

One more parameter is added ("osname") to distinguish Windows Intel drivers from other drivers running on Intel HW.

Very much appreciated! Haven't had the time to implement this myself. Two minor changes are required to make this work across the board, will do that after the merge.

One thing that won't work (yet) is filtering for the converted driver versions, as filtering is done at database level. That's something I'll have to fix at a later point.
