Implement local image caching for static maps

[fireproofsocks]

Basically, we want to have Google generate the static map as desired, then we cache the generated image locally.

See:

• https://developers.google.com/maps/documentation/staticmaps/#quick_example
• http://stackoverflow.com/questions/724391/saving-image-from-php-url
• http://php.net/manual/en/function.copy.php

Big question is whether we can use the Snappy Maps styles in here: https://developers.google.com/maps/documentation/staticmaps/#StyledMaps

As map styles that are generated from the map styling sites like snazzymaps are nothing but json, I dropped them in a system stetting and call gmarker.map_styles and pulled into props array in the snippet. Then I added a placeholder in the gmarkerhead chunk and done. Simple to do the same for gmaps I guess.

Ill fork it and put my changes in so you can see.

Nevermind. Just looked at the latest code and see something similar;) GG
