CreateContent : inherit section

[bchoquet-heliopsis]

I guess it can be considered a bug fix :

• when creating content, the new object section was set to standard by default no matter what section its parent was. It is now inherited from its parent if not manually set.

I also fixed a bug of mine in the CreateSection handler :

• when setting a section identifier and that section already exists, the section object instead of the sectionID was stored in the reference array.

Remembering a similar case in ezpackage, if it isn't done already here it should also verify section id if provided and if it does not exist inherti from parent and write warning or throw.
