[ADD] new_product_type: support for kit products in sale orders
Introduced support for kit products by adding an is kit flag and related sub-products on the product template. Sale order lines have been extended to differentiate between main and sub-products. Sub-products are now handled using related fields and custom logic for display pricing and subtotal computations. Wizard for adding sub-products to main lines introduced. Sub-product lines are made readonly in the UI and their appearance in reports is controlled by a boolean field print in report.
