AV1720: Include local functions

[bkoelman]

Existing rule:

Name methods using a verb or a verb-object pair (AV1720)
Name methods using a verb like Show or a verb-object pair such as ShowDialog. A good name should give a hint on the what of a member, and if possible, the why.
Also, don't include And in the name of a method. It implies that the method is doing more than one thing, which violates the single responsibility principle explained in AV1115.

New language features to consider:

• local functions
  I think this rule applies to local functions as well.

Proposal:

• Replace "methods" with "methods and/or local functions" (in title and text)
• Convert the text-reference to AV1115 into a hyperlink

I thought that we already had cross-reference links between rules. But it appears we do not. Filed #116 to make that possible.
