Interface resolution clauses are now represented in AST

[Wosi]

Resolution clauses like this one:

  TSomeObject = class(TInterfacedObject, ISomeInterface)
  private
    function InternalGetName: String;  
  public
    function ISomeInterface.GetName = InternalGetName;
  end; 

Are now represented like this:

<METHOD begin_line="16" begin_col="5" end_line="17" end_col="5">
  <RESOLUTIONCLAUSE line="16" col="5" name="ISomeInterface.GetName">
    <NAME line="16" col="39" value="InternalGetName"/>
  </RESOLUTIONCLAUSE>
</METHOD>

Hmm...GitHub doesn't seem to recognize the commits that have already been merged previously. Only commit 01d34e1 is relevant for this PR.
