[IMP] mrp: properties on mrp.bom.line

Now it's possible to put a property on a bom line.
For example, the bom for an apple pie and for an apricot pie can be made
in a single bom.
Three lines are necessary in the bom of the product "pie":
	- First line with product " dough" without property
	- Second line, with product "apple" with property "apple" if you want an apple pie
	- Third line, with product "apricot" with property "apricot" if you want an apricot pie

The type of this bom pie must be "set" to allow the customer to assemblate
his favorite pie by himself.

Now to sell an apple pie, you must create a SO with the product "pie" and
the property "apple".

In that way, the delivery order consists of two lines:
	- dough
	- apple
