Thanks for the report. We'll do this in #3962

In 0683d7a2f5581b481737184c1d36f0cc29d8ae0a: Fixes #3964 Adding opera

Still not working:

1. Without DevicesDetection plugin Piwik detects Opera as Chrome
2. With DevicesDetection plugin Piwik detects Opera as Opera Mobile and there is no icon for Opera.
