Setting all current Open Critical and Major to M3

setting paulmac as QA contact for all gagan's bugs (sorry for the spam)

Spence could you see if this is still happens and if so fix it in the tip for dogfood.

Taking over...

Fixed for now. This needs revisiting, since there is a bigger bug about file:// urls in general.

verified that it no longer hangs forever on invalid local file.

Changing all Networking Library/Browser bugs to Networking-Core component for Browser. Occasionally, Bugzilla will burp and cause Verified bugs to reopen when I do this in a bulk change. If this happens, I will fix. ;-)

Bulk move of all Networking-Core (to be deleted component) bugs to new Networking component.
