Renaming parameters so their either use camel case or dash

One discussion that came once on #IRC was "shall we use camel case on the command parameters, or shall we be more 'unixy' and use a dash syntax". At the moment, most of the parameters have the following syntax :

--targetPackage
--targetLocation
--columnName

But a few parameters don't use camel case but the dash syntax :

--not-nullable
--not-insertable
--not-updatable

We should choose one syntax and stick to it.
