Icon pack 26.908.2

Growser icon pack component, version 26.908.2.

Gmail is one brand again (growser#190): mail.google.com was drawn as a brand of
its own beside gmail.com - two drawings, two tile colours, one service wearing
two faces on the same board. The curation now groups them, and the grouping is
honoured for service hosts, which it was not before.

590 brands over 695 domains, 518 drawings.
