[coveralls]

Coverage remained the same at 100.0% when pulling bafa28f on v1.1.0 into bf6bb85 on master.

[curbengh]

Need major bump due to #53 and #55.

[curbengh]

"engines" also need to bump to ">=10.13.0".

---

It's better to include #57. In filter plugin, lower priority value has higher priority, so this plugin should clarify that higher sticky = higher priority.

Edit: #57 merged, remember to rebase.
