#3 Patch gets correct size info for filenames with spaces

[Tim Cera]

The patch uses re.search to go all the way through the
string returned by 'identify' to find the size. The
string.split doesn't work correctly if the filename has
spaces. Could also do something like
string.split(output)[-6], but I wasn't sure whether
'identify' always returned the same number of fields at
the end.

Patch against curator-2.1.

Does anyone read the Sourceforge trackers?
