Pagination

[jay-hankins]

Is your feature request related to a problem? Please describe.
There is/will be too much data to not paginate the ideas feed. The ideas feed should be paginated.

Describe the solution you'd like
Ideally, a configurable number of feed items would be returned, and there should be a pagination component at the end of the feed.

Describe alternatives you've considered
Right now, every single idea feed item is returned.

Additional context
There's pagination build into feathers. By looking at feathers docs and feathers-vuex docs, we can probably get a solution together. There is also a pagination component in spectre css.
