Allow multiple maps on one page in any style (closes #1)

And something bigger.

* Moved most code from `onRun()` to `onRender()`
* Merged Javascript into `default.htm`, and tweaked it to run all map styles
* Fixed caching
* Localization for "Get Directions"

Something strange happend with the `info_small_map` style. If you load the two partials `smallmap.htm` and `popup.htm`, `__SELF__.id` is not correct in `popup.htm`. So i copied the content from `smallmap.htm` to `default.htm` as a workaroud.

I leave the `version.yml` to you. :smile:
