Modifed the OpenCellID methods to only operate if an API Key has been entered through the application settings, enabling each user to request and use their own keys.
This will need to be extended once functionality has been confirmed to provide more instruction to users regarding the registration process, such as through alert dialogs and details regarding the OCID website etc.
Key is stored on the device and only used when initiating communication with the OCID servers, as with all previous versions no personal information is sent to OCID only necessary cell/location information as required by their API methods.
