Feature/116

With this PR, the location and salary filters are being used to build the search query. The other 2 filters are categories and industries, but they don't really map to anything in the searchRequest interface and may still change depending on new designs.

Notes

• Right now if the user doesn't put in an actual number in the salary field, the salaryMin just gets left out of the search request.
• All the latlngs in our database are 0.0, 0.0 since ZipRecruiter's data doesn't contain latlng. So if you actually input a location you won't get any results, but you can check the network log in the chrome developer tools to make sure the search request payload contains latitude, longitude and radius.
