INP-171

1. Fixes #0000189: Changes in Options for "Section Template" field for Sections.

2. Implemented not exactly the way as planned, because administrator can change "Parent Section" from "Content" (top category, where "Inherit from Parent" option in "Template" field not available) to it's child section, where this option should be available. As a result I always show "Inherit from Parent" option, but when administrator manually selects "Inherit from Parent" in "Template" field and "Content" in "Parent Section" field and tries to save changes, I show him an error about that.
