Remove ActiveX from LibreOffice

[Bryan Quigley]

Hi there,

Recently it was decided to remove the rest of NPAPI support [1] which
got me thinking about the other Windows specific plugin tech -
ActiveX.

It seems ActiveX is very much no longer recommended by Microsoft and
it seems to not work by default for IE10/11 on Windows 7 and up.  Any
objections to removing?

AFAICT this would just be removing embedding LO into IE.

Kind regards,
Bryan
