Subject: [PATCH] A configuration setting to use relative symbolic links

Edit the copy function in utils.py to take the parameter rellink and if
it is true, create links relative to the source directory. Modify
gallery.py and __init__.py to pass along this parameter. Add rel_link
flag to setting.py
