Another fix for mirror editing of strand data.
Currently strand edit mode tool use the object data 'x mirror' flag.
This flag is only available on mesh objects, but the strand editing
can be used for dupli override caches etc. as well. Eventually strand
editing should get it's own independent flag to avoid this problem.
