Symbol file should contain module GUID at beginning (#66). r=bryner

- The dumped symbol format now begins with a MODULE line identifying the
   uuid, age, and name of the source pdb file.
 - The processor ignores MODULE lines, but they are useful in figuring out
   how to index symbol files in a symbol store.
 - dump_syms and symupload now both accept either a pdb or exe/dll and
   will read the pdb regardless.
 - Figured out that MSSS always represents a module's age in pathnames in
   hexadecimal, and updated SimpleSymbolSupplier to match.
