Loadfactor for internal pressure can be higher according to NEN3650

Loadfactor for internal pressure can be higher according to NEN3650
Ple4Win assumes that a calculation of loadcase 2 (internal pressure) according to the NEN 3650 has always a loadfactor of 1,25 according to table 2 of NEN3650-2:2003.

This is however not always the case according to NEN3650. This loadfactor is higher for pipelines in a station. See chapter 8.5.2 of NEN3650-2:2003. The loadfactor is then 1,5/1,1. So the current assumption in Ple4Win is wrong in a case when a pipeline is in a station.

I did a request for this:
[796]: [# 25] Allow internal pressure loading factor to have a different value than 1.25 while using NEN3650

So there is a need for adding 2 extra columns in the PRESS table in function 4,2. Default values could be set to 1,25.
