Collapse all the inactive pools

[AndruAllen]

Is your feature request related to a problem? Please describe.
With more pools being added and old pools becoming inactive, the farming tab is becoming crowded.

Describe the solution you'd like
Design a dropdown for inactive pools that a user doesn't have any funds in. It would allow all of the inactive pools to default to not being show unless the dropdown was expanded.

Describe alternatives you've considered
Remove any inactive pools from the farm page that a user doesn't have any funds in. Inactive pools are crowding the UI and if a user has no funds in them then there is no reason they would want to deposit new funds into them.
