ForeignKey filterspec

Unfortunately, it is not possible currently to use foreign keys in list filter of the admin website. list_filter=['city__country'] doesn't work. This filter spec tries to workaround this problem. It is also possible to have 2 filters for a foreign-key field but it requires to add a dummy field to the model. Set the fk_filterspec dictionnary on this dummy field and add 'fk':'real-field' to the dict.

Number generator to autofill a field

**Number format:** number/year **Purpose:** When the user adds a new bill, the "number" field will be automatically filled with the appropriate number. * The snippet automatically increments the bill number based in the highest number available. This is because in the use case, the user could start by *any* number, and we couldn't use the PK number (p.e. if the user first object number is 324/10, using the PK will convert it to 1/10) **NOTE:** bill_type is a Boolean value to mark if the bill is outgoing or ingoing. Since we only need to mark the outgoing ones, we filter through this field.
