Polish the Enumerate Modules implementation a bit.

1) De-dup the registered DLLs since a lot of the same DLLs will be registered multiple times, ie. mswsock.dll
2) Every module loaded from a %temp% dir should be viewed as suspicious.
3) Add some histogram counters (xml changes coming in a followup CL).
