Adds some regex to the image filter to make sure we don't transform things that are already img tags.

Helpful when using redcarpet in front of the image filter.

use a static date in gemspec
Add type, zoom and show_info parameters to google_map filter.
Remove gem.date from the gemspec.

This was causing errors when deploying to engine yard and heroku. I've seen many

'date' to the gemspec, but I find setting gem.date to today's date somewhat
useless.
