Finally got ChromeOS icon/toltip working!

It appears its matching based on the class, not the application.
Since this was hard-coded to CIOLIB based on the idea of using
resources to customize all CIOLIB windows, this didn't match the
SyncTERM .desktop file, so ChromeOS assumed it was "something else"

Add yet another ciolib_initial_* variable to set this, and she's
finally good!
