Description

Having a table named ".META." causes problems on NTFS file system under windows, since it does not allow file names ending with ".".

Nicolas and I have been thinking of just changing the name of the META to be

-META-

Since 0.96 is the singularity, and we already moved ROOT to zk, now seems like a good time to do such a change. There will be no rolling upgrade support.

We can migrate META, and can keep BC, by having an internal alias between the old meta name, and new meta name. This way, outside scripts and code who reads META can still work.
