Adding includes to top of securitymanager.md.vtl
This was one of those expensive lines, I had no idea why the tags were not getting rendered.
I'm guessing there is some state in `scms` that once the includes macro's get added they rendered even in other files
And if you process the files in a different order that could cause problems (just a guess)
diff --git a/securitymanager.md.vtl b/securitymanager.md.vtl
