Add description property to Section and EntryTypes

Description

At Newism we've been discussing ways to better self document the CraftCMS control panel.

I noticed that UserGroups have descriptions but Sections and EntryTypes do not so I added them.

There's no front end display of these values yet – open to discussion. The values could be used in custom UI elements at the discretion of the developer.

One thing that could throw a spanner in the works… what happens when a new property is added to a model and there's an existing custom field with the same handle?

• Added craft\models\Section::description
• Added craft\models\EntryTypes::description

There would need to be an obvious place to show the description in the core UI for this to be seriously considered.
