Extend support for financial_types into various tables

This issue extends support for financial types and thus financial accounts into areas where it was previously needed but missing. It covers configuring financial_type_id values but for the most part not dealing with them during the creation or updating of transactional information.

Add a financial_type_id field to the appropriate files in xml/schema:
civicrm_price_field_value (Revenue)
civicrm_line_item (Revenue)
civicrm_grant (Expense)
civicrm_contribution_recur (Revenue)
civicrm_premiums_products (Expense)
civicrm_contribution_product (Expense)
civicrm_product (Expense)

Make a validation that will return errors if there is no entity_financial_account.relationship of the types in the parentheses above for the financial_type selected.

Create upgrade scripts to alter the tables so that the fields allow Null. Joe to spec the choice of financial_type_id to put into each field. After the fields are updated with values, change the fields to required / not null.

Change the UI for the fields as follows (required field in all cases except for grant sometimes - see details below):
civicrm_price_field_value:

• Put column between Default and Order on civicrm/admin/price/field/option?action=browse.
• Put field between Description and Participants Count on civicrm/admin/price/field/option?reset=1&action=update
• Default value of new price_field_value.financial_type_id to the session's most recent price_field_value.financial_type_id
  civicrm_price_field
• Put column between Field Type and Order on civicrm/admin/price/field?action=browse
• Put field between Display Amount and Order on civicrm/admin/price/field?action=update
• Default to - select -

civicrm_line_item

• No UI. Fill with value from related price_field_value record.

civicrm_grant

• Between Money Transferred and Grant Report Due on civicrm/grant/add
• only required if there is non-null date for Money Transferred and non-zero Amount Granted
• Andrew to specify how to record this

civicrm_contribution_recur

• No UI: pull from contribution_page.financial_type_id at time recurring contribution is set up.

civicrm_product

• Put field between Actual Cost of Product and Options on civicrm/admin/contribute/managePremiums?action=update. This is a default value for the financial_type for how to handle it when it is included in premiums for a page.

civicrm_premiums_products

• Put a financial_type field between Select the Product and Weight on civicrm/admin/contribute/addProductToPage?action=update&id=1&pid=1&reset=1
  • As the 'Select a Product' field is changed, the financial_type will be updated to show a default value of the related civicrm_product. This default value can be changed to a different financial_type.
• Put a column between Min Contribution and Weight on civicrm/admin/contribute/premium?action=update&reset=1&id=1

civicrm_contribution_product

• No UI: pull from civicrm_premiums_products at time of contribution.
