Child subscription paid to date is calculated
from days added to Parrent subscription.
Days that single payment adds are substracted from
days to add to Parent subscription. This is "virtualy" payment
date. Single payment days of child subscription is added to
virtual payment date.

Some users might found Dynamic pricing of payments missleading
as normal access fee can be paid with dynamic pricing, but
reorrucing custom invoice recalls flat rate.

This commit changes custom invoice logic so that it allows
dynamic pricing. Minimium payment is calculated from service
minimum payment * service payment times.

It can be disabled from settings.py or constance admin panel

Child service is paid by calling funcion again. So now if child
service has childs, they get paid.

Updated calcultaion so that multpile custominvoices
wont break basic idea of child payments.

Updated transaction commenting so that steps of transaction
is easy to read

With my childservice paymentlogic user could see increase of paid_to date.
For example with initial transaction extradays are added to parent
and chid services. It could be that shildservice after next payment is
paid more to future than new transaction gives. This commit fixes that.

Added support for childservice to pe paid indepentendly.
Useful if member want to pay membership and parent service is
intentionally suspended.

If user banktransfers are recalculated transaction comments
would multiply. So cleaning lines before recalcultaion keeps
comments tidy.
