[Dbix-class] is_nullable

[Dermot]

Hi,

I notice that when I use DBIx::Class::Schema::Loader it always creates
the columns as is_nullable => 0.

Is this by design or is there an option I can pass it so that my
ResultSources will maintain their 'NOT NULL'.

I only ask because I used deploy for testing today and it created the
schema as per the Sources and that took some fiddling to correct.

I am use SQLite 3.5.1

Thanx,
Dp.
