No sqlite3 causes issue on import of PaginatedQuery
Aha, thanks! Should be fixed by f68ff7fb30a149fe9df8050b8001a1b4d3636bec This fix didn't work -- the error still happens because an AttributeError is the problem, the fix catches an ImportError.

If you look at the file `sqlite_ext.py`, line 54 `from peewee import sqlite3`
Then looking at lines 155-165 in `peewee.py` `sqlite3` gets set to `None` if I don't have pysq3 or sqlite3, which I apparently don't have. :)

Again super appreciative of all the help and quick fixes. Thanks again.

 Is the traceback the same?

```
FTS_VER = sqlite3.sqlite_version_info[:3] >= (3, 7, 4) and 'FTS4' or 'FTS3'
AttributeError: 'NoneType' object has no attribute 'sqlite_version_info'
``` Yes, I believe so, here's the full traceback (using a fresh pip install of 2.9.1):

```

``` Could you try the latest commit, fc84b65ff3a02eba05ccf63aead2de38412ac9c3 and let me know how it works? Sorry for the bad fix! Hi -- just checking in. This fix hasn't made it in to the latest version yet, afaict, on install from pip. I do see it is in the master repo, though. It should be in 2.9.2. got it! thanks!

 Still facing the sqlite3 issue, even though we are using peewee==2.10.1. Please advice at the earliest. Thank you.

I use MySQL and don't need sqlite3.

`from playhouse.flask_utils import PaginatedQuery`

gives me this error:
```
FTS_VER = sqlite3.sqlite_version_info[:3] >= (3, 7, 4) and 'FTS4' or 'FTS3'
AttributeError: 'NoneType' object has no attribute 'sqlite_version_info'
```
[line that causes error](https://github.com/coleifer/peewee/blob/f3795767f7b46c8b5335ea0257df2a1d269fc85b/playhouse/sqlite_ext.py#L70)

I'm in the google app engine development environment, so I believe sqlite3 gets set to `None` when the `ImportError` is caught.  My hacky fix is an if/else setting `FTS_VER` to `None` if there's no `sqlite3`.
