1. In lexer, parser, and debugger code, renamed column to charPosition.
2. Convert the charPosition to the equivalent column number before
   passing it to the debugger.
3. Changed ScopeNodes to take both a startLocation and an endLocation.
   This allows FunctionBodyNodes, ProgramNodes, and EvalNodess to emit
   correct debug hooks with correct starting line and column numbers.
4. Fixed the Lexer to not reset the charPosition (previously
   columnNumber) in Lexer::lex().
