Bump AssemblyVersion to 2.7.5.0.

Add publisher policy files to redirect 2.7.0.40 to 2.7.5.0. Anything
that links against 2.7.0.40 will redirect to 2.7.5.0 (as they would
anyway if the existing 2.7.0.40 was just replaced) but anything that
links against 2.7.5.0 will not accidentally link against an old version
of 2.7.0.40.
Add publisher policy files to installer.
