[functions list, Ruby] fix name of class methods defined as self.method

Description of the Feature

Current behavior

Currently, class methods, defined with self.method, all get self as their function name.

Desired behavior

Instead of self, it would be nice if they get a proper name (in case of a method definition like def self.method: either the actual method name (method) or its definition name (self.method)).

A solution using the definition name can be accomplished by changing the following:

mainExpr="^\s*def\s+\w+"

to

mainExpr="(^\s*def\s+self\.\w+)|(^\s*def\s+\w+)"

Platform information

Notepad++ v7.1 (32-bit) on Windows 10.

Open PowerEditor/src/functionList.xml and inspect the Ruby function-list entries around the referenced lines. Update the matching expressions so definitions using self.method receive the intended name while ordinary methods remain recognized, then verify both forms in the editor's function list.
