Unnecessary disk space requirements for tag editing

This latest update to 0.30 seems to have “broken” one previously functional ability. Now, when trying to edit tags for a file, Subler errors out if there isn’t free space on the volume equivalent to the size of the file.

So, for example, if changing the tags of a 10GB file and the drive has 1GB free, it errors out. This never happened in previous versions (and, if simply changing a tag, there’s no reason for this to happen!).
