Switch the menu buttons from images to text with css.

This change would be better for accessibility and translations, and would allow to add new menu entries more easily.

I've asked Matthias for a screenshot since I don't have an installation at my disposal anymore to check this. I'm fine with this as long as the overall appearance hasn't changed.

Before, with images:

After, with CSS:

Wonderful. This looks fantastic. Thank you for doing this.

@veggiematts This is a great help, thanks for your work on this. I will push this into master, but I'd like to make a few small changes. First, I want to change the tags to tags, since those are more standard when using normal links (instead of a form). I will also make the necessary style changes to keep the appearance the same. Second, I want to make the "selected" menu item more visible by making the background color a little darker. Since these are small changes, I will push them into master now. But if you have a reason for using the tag, please tell me and we can make changes as needed.

NOTE: The other modules will need this same kind of change. Also, it would be good to replace the "Change Module" drop down menu images with text.

Thanks Remington. Great points about the other modules and the Change Module dropdown.

Yes, this is excellent and a long over-due change. I can modify the usage stats since I'm about to put in some changes to that module.
