New scripts from unagi-trunk

These scripts are all from [the official Sourceforge repo](http://sourceforge.jp/projects/unagi/scm/svn/tree/head/client/trunk/anago/), but haven't yet made it in to an official release (the latest release seems to be from March 2010).

As they are "official", I did not change the names at all.

Do these scripts belong here, or would it be better to maybe just add a link to the Sourceforge page where they can be found?
