Add location support

[mohit2530]

Adds location support for home page. Users who do not choose a default location will be provided with standard 0,0 location and users are able to retrieve their approximate location based on the browser navigator.

• add support to fetch nearby location in search bar and display updated location in the map
• tech debt and css cleanup for components related to location and events
• update map center to be based on user location / default behavior.

Redirecting should not have to repopulate the location, can we just use local storage to manage this ?

I think I agree here, using local storage to store the client location, we get the benefit of having the location at all times and the user does not have to click the button all the time.
