This key allows users to pass an arbitrary amount of queries
that contain custom filters. A simple query that shows all closed
PRs could be written like the following.
```
customQueries:
closedPullRequests:
title: "Closed Requests"
perPage: 10
filter:
- "is:closed"
- "is:pr"
```
Resolves#469
Currently, we are only getting a subset of PRs. For very active repos, this might mean I don't see any of my PRs
This isn't an explicit fix (iterating through pages would be), but at least lessens the problem
