Migrating legacy umbraco_form_picker. Shouldn't it be picked up as a macro? #274
Description
Realising after @ronaldbarendse helped with sorting out a legacy grid migration.
The old school "umbraco_form_picker" grid editor that was added as part of legacy forms doesnt get correctly migrated by the base MigrateGridControl method.
Considering the legacy picker was essentially just a macro embed, would it make sense to have the current switch statement consider umbraco_form_picker alias as a macro and run them through the base implementation by default?
Otherwise by default it simply dumps them into a textarea.
