Feature/services filter

what is this? this is a new Availability - WMS_Service collection filter in the tool drawer.

methodology I manually fudged in the input checkbox html in the collectionFilter component feeding it the same capabilities/functions as the other automatically created filter input checkboxes below this one. then in the collectionSelectors, the getFilteredCollections method handles the logic to specifically check for the 'WMS_Service' filter being set first, and then checks for all collection ids with a valid wms_link property before adding those collection ids to the filteredCollectionIds or multiFilteredCollectionIds array.

i need this one tested out pretty good before we merge it. i've run through it a couple dozen times and it seems to behave properly but i want to make sure its solid.

there is probably a better way to do this and i'm open to suggestions for ways to re-factor or change this functionality. its seems to work pretty good though I think. take a look and let me know what yall think. we can push new commits and change this if you guys think we should. whatever works best.

thanks.

oh, one note. if you set the Download filter and then set the new __WMS_Service filter, there isn't a change in the number of collections because all collections with wms services are available for download. there may be a valid point to put this filter somewhere else other than within the Availability__ filters. I don't know...
