Removed resolving of "path" in "watch to Enable chokidar multiple file watching

chokidar watch supports multiple folders/files watching so I mosified the watchPath variable initialization.

chokidar.watch( <path / [paths] / [folders]>, <options>)

I also updated Task.prototype.writeWatchingMessage so that it will indicate how many folders/files are being watched if you have specified an array as the path variable.
