The below tested patch makes the previously harcoded limit of 100 items in a RESTful API response configurable in the Administration GUI. The default value is still 100. This is based on 2.4.1.stable.

This is quite useful since it is nice and simple to just get the full response in a single page rather than having to traverse pagination, and a limit of a bit more than 100 is still very performant for many sites -- the limit beyond which performance starts to degrade really depends on the particular site's usage, so should be controllable by the local administrator.
