Error on single quotes within tag names

[kbruland]

Errors are thrown on the photo.setTags and photo.addTags methods when the tags value posted contains single quotes. This appears to be because these are encoded within the post body. When a tag value containing a single quote is entered manually within the Flickr UI, the single quote in the resulting underlying API call's post body is not encoded and works.

thanks for reporting! marking as bug, although I don't know when I'll be able to get to fixing it.
