fix typo - change conn to con
Noticed a typo in the documentation of `write_frame`.

Method def has `con` while documentation had `conn`.

`def write_frame(frame, name, con, flavor='sqlite', if_exists='fail', **kwargs):`

Convention generally is to call connection `conn` and not `con`, so maybe the fix should go in the other direction. e.g. [in the Python docs for sqlite3](http://docs.python.org/2/library/sqlite3.html).
 I agree and just made the change, however now that I pushed the change I went back and looked the rest of the file and it seems to use `con` for everything.

So I think I'll push back only the documentation update, however I'd be happy to revise the entire file... 
 good call

 @tshauck Thanks for finding/fixing this!

Do you mind deleting the last two commits or rebase squashing the last three? so either

```
git reset --hard HEAD~2
```

or

```
git rebase -i HEAD~3
```
 @hayd Happy to do it... I just pushed the change.
 Awesome, thanks!
