Multiple --watchDirectory options throws error

[alex7071]

This comes from the forever cli project but issue is in the monitor watcher plugin:

Scenario: include multiple --watchDirectory='somepaths' in a forever start command.

Expected: watch multiple directories
Actual: throws exception:
TypeError: Path must be a string. Received [ '/var/www/myproject/services/engine',
'/var/www/myproject/lib/nodejs' ]

It's constructed as a string array as chokidar requests but the watcher plugin throws an exception on line 54 when this.watchDirectory is a string array. It expects a string.

Didn't have time to see if multiple .foreverignore would work, but IMO, the watcher plugin should either iterate through items and use multiple .foreverignore files or use a '.foreverignore' in a single location of the command context instead of the watchDirectory.

LE: watchFilter uses this.watchDirectory too, so that needs fixing as well, so it works with array.
