Feature summary (what you would like to be able to do and where):
Pagination support for wikimedia geosearch api. In other words, similar to other lists, "continue" parameter should be returned when the returned result is not complete.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
I was querying wikipedia articles near me, and realized that I could only query 500 articles at a time. There is no way to query for the rest of the locations because no continue parameter was returned. See here for example.

Benefits (why should this be implemented?):
Allow complete querying of articles near by, especially in areas where is a high concentration of articles.
