Propossed Improvements

Hi,

I have made some improvements on your plugin so maybe you can add them to the official package master.

The list or improvements are:

- More Field Types
- On Clicked on the map addres field (and other ones) are filled
- posibility to fill address with full formated or a simple version one (street name and number)
- When no location is defined or is equal to 0,0 location is taken from the browser

Also i have documented the README

Regards.
