Better indication of long term stats request (update pace.js?)

[bernhardreiter]

Fody v0.9.3 uses https://github.com/CodeByZach/pace (probably v0.4.6 from 2013),
one user reported that on a very long stats request (54 Minutes) the progress bar and working animation vanished.

When testing this, a new version of pace could be considered. Maybe even thinking about collecting it via yarn.
