Disable OL 2013 / 2016 resiliency for us
* src/gpgoladdin.cpp (setupDoNotDisable): New. (addGpgOLToReg): New helper.
While this should not be necessrary if we don't crash, well
in the real world it happens and then users have the problem
that they have to manually renable GpgOL and report it
as an issue.
With this GpgOL should no longer be disabled in Outlook
2013 and 2016. 2010 does not have this auto disable.
