Node8

This was made to rollback to nodejs 8, the last version who can be installed on system i386.

Yes, as all we run following the versions, but in our case, it's better to think at the platform we can serve the the news of the nodejs.

Thanx to be back to node v. 8 we can restart to produce packages deb in i386 version.

Well. all the changes are in the class n8 and changment only in ovary.ts.

Probably there is a problem with the cli installer, we will solve it soon.
