Added support for uploading surveys to the server. The server will store the received results in a csv format for later usage. Also added the ability to specify the servers location from within the settings menu. This will allow a user to specify their own server if they desire. A column has been added to the Survey table as well to keep track of whether a particular survey has been uploaded or not. Performing a long press on the survey explorer page will present the context menu with the upload option. #9
