import from multisite gallery2 fails with a blank page

[dkmp]

Looks like the import process is not ready to import gallery2 configured
for multisite. The process tries to copy and change embed.php, which does
not contain what the script is expecting: the embed.php for a ms install
simply "requires" the master embed.php.

Result is a blank page (no error in g3's log or in apache's log)

You can find a potential fix in http://github.com/dkm/gallery3/tree/master
I tried to do things clean, but I'm not a php hackers... At least, it works for me.

I wrongly reported the bug here: https://sourceforge.net/tracker/?func=detail&aid=2803348&group_id=7130&atid=107130
