line_item table should be updated when contribution financial type is changed.

Add a Contribution edit form rule that prevents Financial Type from being changed unless all line items have the same financial type as the contribution. Error message: 'One or more line items have a different financial type than the contribution. Editing the financial type is not yet supported in this situation.'

Original Description:

When you edit a contribution by changing the financial type, contribution.financial_type_id is updated; financial_item.financial_account_id is updated but line_item.financial_type_id is not updated.

This breaks the 'link' there should be between the financial_item.financial account _id and the line_item.financial_type_id

I consider the introduction of inconsistencies between tables in the DB to be a major problem.

I have not confirmed this on a demo site as the extended report extension is not installed on them, so the only way I know to check is to look in the database.

I have confirmed this happens on both my 4.4.12 and 4.6 alpha7 installs.
