Change column Page.data to Text in wiki2 tutorial

[viniciusban]

Column data in Page class is Integer but should be Text in wiki2 tutorial.

How'd that get through? Anyway, nice catch. LGTM

[viniciusban]

Because of this: http://www.sqlite.org/different.html

tl;dr: almost everything is stored as string. See the "Manifest typing" section.

I'm aware of sqlite's typing issues but usually SQLAlchemy will complain somewhere along the lines. In this case it looks like it just shuffles along the data from the driver however.

[viniciusban]

Indeed. :-(

Huh, that's interesting. Using PyCharm's database browser on the database tutorial.sqlite, it shows data as type INTEGER. I expected TEXT.

I'll want to review all these docs again as I am certain there are more occurrences such as in the output of database initialization, but I'll create a new issue and do that in another PR.
