Completion order

[trikko]

I think completion order can be improved in some ways.

For example giving higher priority to:

• Methods / properties not in parent classes (that more likely I don't know, but I need!)
• Overridden methods (that's why I'm using this class and not its parent, probably)
• Recently used fields/methods

And lower priority to:

• Undocumented methods
• Fields starting with _
