Make CIText inherit types.Concatenable

[brmzkw]

This code:

>> from sqlalchemy import Column
>> from citext import CIText
>> print Column(CIText, name="field") + "whatever"

Without the inheritance, generates the invalid syntax:

field + :field_1

With the inheritance, generates a valid, working syntax:

field || :field_1

It is also problematic if you need to use "startswith":

>>> print Column(CIText, name="myfield").startswith("ABC")
myfield LIKE :myfield_1 + '%%'

Note you can still transform the filter to a literal as a workaround.

>>> print Column(CIText, name="myfield").startswith(literal("ABC"))
myfield LIKE :myfield_1 || '%%'

@brmzkw this is sweet! I'll merge this when I can but first I think it's time I write a test suite for this package. Want to start it off? If not, I can do it either today or tomorrow.

[brmzkw]

I'll try to write some tests tomorrow, and will create another pull request :)

[brmzkw]

Done

Is it possible to push a release on pypi? :)
It would be cool to have a Changelog, too!

[mahmoudimus]

Yep, I'll push a release :)

[mahmoudimus]

Agree re: changelog, will get started on one. Want to create a follow up github issue?
