This feature was never publicly released, and has not been distributed
in our binary builds for a couple versions now. It needed to be removed
in order to reduce the number of places Nmap looks for data files. See #2051
Changes:
* Fix a collision of the name PS_NONE with a different constant in shlobj.h
* Update solution and project files for VS2013
* Update the NSIS installer to reference the VC 2013 redistributable
Make new versioned nmap.rc.in and nsis/Nmap.nsi.in, and use those to
generate unversioned nmap.rc and nsis/Nmap.nsi. The changes made to
those files were constantly causing problems with updating.
