Filter tool improvements

[HelenwoodsJNCC]

Hi @andyb-esdm @SimonAnnetts,

I'm wondering if it's possible to make a few hopefully simple improvements to the filtering functionality to improve the user experience:

1. When you click on the filter button the pop-up window closes so the user knows something has happened
2. Where there are multiple filter options on a layer is it possible to order the filters? Currently the order of them seems to change - it would be useful if we could control which order they appeared in.

@andyb-esdm @SimonAnnetts - any thoughts on this?

@HelenwoodsJNCC sorry for the delay in our reply.

1. This should be easy to change
2. We can add a SortOrder column to the filter table and send a sorted list of filters back to the map.
   See Distance/Area tool #107 for scheduling the work

@HelenwoodsJNCC This is implemented now. We're going to discuss deployment later this afternoon with JNCC IT team.

Hi @andyb-esdm, obviously I can't test the filter ordering but the simple apply-close functionality seems to be working fine.

@HelenwoodsJNCC Simon and I tested this 'live' (he changed the order in the database and then we refreshed the page). So we're pretty confident it works. It uses a similar mechanism to ordering the layers.
If you have any issues when staged we can fix it then - but we should be okay (famous last words ...).
