Add request priority and initiator to the HAR

[paulirish]

Prefixed with an underscore as they are custom, nonstandard fields

Thanks, there is an _initiator field already, but it is a child of the entry. I think that initiator and priority are more related to the object itself rather than the request. What do you think?

P.S. Since you're rebasing in any case, do you mind putting the chmod +x in a separate commit?

[paulirish]

Hah. Sorry I had missed the initiator completely. That's excellent.

Yes I'll nuke my initiator change and separate the mode change. Cheers

updated.

Great, thank you! I moved the _priority field outside the request object though; I think it makes more sense there, for what concerns the HAR context.

[paulirish]

Cool. Works for me!
