Really simple error handling for Piwik fetching
Forget that Piwik fetching, include a local copy

Doesn’t work reliably.
Longer HTML caching
Make gulp tasks wait for each other

Okay, I feel like a total n00b now.
Make Piwik ID dynamic, put it in pageinfo

Preparations for multiple environments.
Access Piwik via HTTPS only
Convert to “stage” and “live” environment

I hope that this is stable, I’ve changed quite a lot.
