[photran-dev] Refactoring Engine Refactored

[Jeffrey Overbey <subscribe-photran-dev@xxxxxxxxxxxx>]

I completely refactored the refactoring engine, and the result is in 
HEAD.  To parse a program for the model, use the FortranProcessor; for 
refactoring, a parse tree, or a symbol table, use a 
RefactoringFortranProcessor, which is in the refactoring package.  All 
of the methods that used to be static in ParseTreeSearcher and 
ProgramEditor are now instance methods in AbstractParseTreeNode, 
ParseTreeNode, or PartialProgram classes.  If anyone's code breaks, let 
me know, and I'll tell you where the "missing" methods went.

Also, the parser is no longer in a jar, so you can delete the 
org.eclipse.photran-parser project from your workspace.

Spiros -- I pulled your latest IntroduceImplicitNoneRefactoring from 
HEAD and converted it, but there's no green bar; did I break it?
