Merge pull request #149 from sprowell/master

Fixed bad file name.
Removed old def operator.  It's been deprecated for a while now; should not be a surprise to anyone.
Removed `BasicAtom.traceMatching` and associated methods from `BasicAtom`.  Removed `tracematch` operator from `Core.eli`.  Everything now uses `Debugger` with tag `"matching"`.
Removed `ERepl.useConsoleColoring` and replaced it with the __property__ `syntaxcolor`.  Renamed the `syntaxColoring` operator to `syntax_coloring` and made it take a flag, to conform with the other operators.
