Make copy friendlier with option not to blow away existing dirs

Browse source 
Let's play nice.  Now when using copyDirSyncRecursive, you can pass an optional opts object.  If this object contains a preserve member, then the function will preserve exisiting directories and only overwrite existing files within the directories.  Without passing the option it behaves the same as always
