EnumerateModules: Address UI review comments.
Make it a simple list with columns. Sort by status (conflicts at the
top), then by location and module name. Also, convert the type of DLL
to an enum so we can dedup the list (and for non-loaded DLLs show that
they are not loaded yet, but are of type: Shell Extension / WinSock.
Make sure lower bound version specified on the blacklist is inclusive
(first version that broke) and the higher bound version is exclusive
(first version that worked).
This allows us to pointpoint exactly when the failure started and
when the fix was introduced, instead of doing 0.9999 shenanigans.
Specify an upper bound for the idmmbc.dll conflict, since Henry's
outreach produced a fix in version 6.03 of the download manager.
