update_self

Added the update_self method, which is an alternative to the save method. Here's an example where it's useful:

# If we have a band object:
>>> band = await Band.objects().get(name="Pythonistas")
>>> band.popularity
1000

# We can increment the popularity, based on the current value in the
# database:
>>> await band.update_self({
...     Band.popularity: Band.popularity + 1
... })

# The new value is set on the object:
>>> band.popularity
1001

# It's safer than using the `save` method, because the popularity value on
# the object might be out of date with what's in the database:
band.popularity += 1
await band.save()

Thanks to @trondhindenes for suggesting this feature.

Batch raw queries

The batch method can now be used with raw queries. For example:

async with await MyTable.raw("SELECT * FROM my_table").batch() as batch:
    async for _batch in batch:
        print(_batch)

This is useful when you expect a raw query to return a lot of data.
