We needed to abandon Avastar 1.5-6

We found a serious issue with the Avastar-1.5 Release.
It does not look like we can fix that within a few days.
Because of that we have removed Avastar-1.5 and
reverted to Avastar-1.4-9

Should you already have downloaded avastar-1.5 then we
recommend that you no longer use it.

We are very sorry for this, but this bug survived all our
tests until today.
