Short description of error

The Description edit box for a new created keying set is disabled.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Open Blender. In Properties Editor go to Scene. Open the Keying Sets tab and create a new keying set.

The Description edit box will appear. But it is not editable. Means you can't add a description to your new keying set. And there is nothing to read since you can't add a description to your new keying set.

@Brecht Van Lommel (brecht) I'm unsure how this is supposed to work. Is this a bug or not? It's the same in 2.79 and the tooltip seems to indicate that this is intended.

I'm not sure what this property is supposed to do. bl_ properties are intended to be defined by Python classes, I don't know why this is in the UI.

@Joshua Leung (aligorith), do you know what this is supposed to do?

Hmm... I didn't really recall adding this. A quick git blame shows that it was introduced in rBa80b7d612947e1d26b10165a37bb603dae527afd by @Bastien Montagne (mont29)

I agree this could be useful functionality to have, so we could just rename the KeyingSet.bl_description RNA property to KeyingSet.description (i.e. dropping the prefix). That shouldn't break the Python-defined KeyingSets registration (since that uses the KeyingSetInfo struct instead)

Naming is indeed rather wrong here… but this is not the reason of the problem, it's a stupid mistake in prop flags. I'd rather not change name for now, will just fix the actual issue.
