Added Fix for not all records being displayed.

I was able to fix this issue by adding pagination to the API url. This expands results from the default of 20 to the max of 100. If anyone has a project with more than 100 issues/results right now there is no fix and you'll need to rely on filters then add them up.

You can see this function of the api described here: https://docs.gitlab.com/ee/api/README.html#pagination
