Add 'hl' parameter to allow the map to translate itself. (Part of #314777.)

Remove the markerdata hack.
Add a marker file generator and fix markers once and for all.

#279049 reported by tormi: Use a valid variable for the author map marker. (You can now choose a marker by going to "configure" for the author map block.)

Fix minor issue with node type names. (This technically prevents XSS with content type names, but if you're giving out the ability to create / edit content types to people you don't trust, you have much bigger problems.)

So, by popular demand, I'm adding a CSS rule for that.

Tested in Seamonkey and IE6.

Fixing align brokenness noted in comment 66 of #266595. I was treating a string as an array and accidentally stomping some css classes.

Make a slight change to how gmap element processing works. This should reduce warnings.
Add some tests.

Note: The old "small red" and "small blue" have been renamed to "alt small red" and "alt small blue"! If you were using these two markers in macros, and wish to keep the same look as before, please update your macros.
The new markers have thinner borders.

#310357 reported by bobchristenson: Remove code that makes map/node 404 if there weren't any results.
#310365 reported by bobchristenson: Fix "map/nodes" typo in fieldset title.

* Reduce the number of variables used by the location map block.

Since I keep making the mistake of using comma delimited behaviors in macros, we might as well support the syntax.
