Support for "rename table"

[chvanikoff]

There should be a possibility to rename tables in migrations, like with Postgres or Mysql:
rename table(:old), to: table(:new)

[AndrewDryga]

This is definitely should be supported, I wasn't able to find a native way for a table renaming, so some emulation should be done.

Yep, I believe the only thing Mnesia supports is:

1. create new table with same structure but new name
2. Copy data over from old table to new table
3. Destroy old table
