Add paging for query results

[joewiz]

Currently query results are truncated to 10 items, with no mechanism to page through additional results.

Adding previous & next commands would be great. Exposing these via toolbar (see #53) would natural.

Adding a setting for the number of results per page would also be convenient.

actually I think the way query results are handled is in need of an overhaul. There should not be a query-results file that appears in the repo in certain conditions, but not others.
But first we need @wolfgangmm to add his token to travis ;-)

What do you mean by "appears... in certain conditions, but not others"? For me, query results always appear in a new (unsaved) editor pane labeled "query-result" in the lower half of Atom's window.

yes and sometime they are written to a tmp location and sometimes into the code repo I'm currently working on

Without you hitting save? Reproducible? Sounds like a bug - sufficiently different from the issue here that it’s worth its own issue.
