[web2py] Suggested patch to DAL

[brad]

I'm not sure how best to submit patches.

I have a small fix to dal.py to fix a problem when MySQL backends are
given a table definition having only the implicit primary key field:

My patch queue is at https://brado...@bitbucket.org/bradobro/web2py_patches,
and there are some notes its wiki.
