Seafile pro edition 7.0.7 is ready!

No clue what I’m doing here (no experience w/ Python) but I created an .egg from SQLAlchemy 1.1.18 (the last one ín the 1.1.x branch) and use that instead of the old one (keeping the 1.1.3 naming as there was another dependency I couldn’t find).

The log spamming has stopped now. Let’s wait for unwanted side effects but maybe @daniel.pan should just upgrade SQLAlchemy in 7.0.8?
