zip file contains hidden .svn and Mac OS directories

```
The zip file here:
http://gridfocus-wordpress.googlecode.com/files/gridfocus-v1.5b.zip

contains a .svn directory under images/ -- this causes problems for some users.

Also, the zip contains a __MACOS directory and .DS_Store files, which cause
clutter but not problems.
