Stop trying to access NSMutableArray

Unfortunately the private structure of NSMutableArray changes
considerably between versions of iOS. (see http://git.io/CAbScg)

I tried to fix this by using ksobjc_getIvarValue, because the
field names have stayed constant throughout, but unfortunately
NSMutableArray uses bit-packing for flags which is not supported
by ksobjc_getIvarValue (or Apple's object_getInstanceVariable
for that matter).

For now I think the safest thing to do is to not dig into mutable
arrays.

Export vmaddr for images

You need to subtract image_add and add image_vmaddr in order to look
up symbols using atos or similar.

At Bugsnag we use this to display useful addresses on the website in
the case that we don't have a dSYM.

Issue #75: Add support for the Quincy 3 server.  The QuincyKit now supports a user name in addition to a user ID.  That is added.  Add support for the new XML elements in the Quincy 3 report format.  Change the x86 tag on binary images to i386 so that the Quincy sever will parse the reports.
