[Zope-PAS] merge r70450 to 1.4 branch?

[Rob Miller]

gmane appears to be lagging... apologies if this comes through twice...

hi all,

i made a very small fix on the trunk some while ago to allow PAS to support
image type properties on UserPropertySheets
(http://svn.zope.org/PluggableAuthService/trunk/UserPropertySheet.py?rev=70450&view=rev).

i forgot, however, to merge it onto the 1.4 branch at the time.  is this
change minimal enough to make it onto the maintenance branch?
