Table name quoting

[Digenis]

Tables names that don't start with a letter or aren't alphanumeric
need to be enclosed in double quotes.

Thanks a lot for the PR!

CHANGELOG / tweet?

Btw @tmylk build fails -- related to repo move?

@Digenis Test fails in Python 2.6 probably because asserts need to be backported

ERROR: Irregular table names need to be quoted

Traceback (most recent call last):

I just looked into it.

I thought that you should get a different traceback in 2.6 — it lacks assertRaisesRegexp.
Then I noticed tests/accessories.py, it has an incomplete implementation of assertRaisesRegexp
which can work only as a context manager.

I fixed it, you can git pull git@github.com:Digenis/sqlitedict.git master
to avoid PR formalities.

Also, in python-3.something, it should warn about renaming it to assertRaisesRegex.
