add params for PermissionTarget.__init__

[donhui]

In some cases, we want to customize the parameters: includesPattern and excludesPattern. So them needed to be exposed to developers.

I think we're able to change it after initialization like this

obj = Obj()
obj.includesPattern = "what-we-need-to"
obj.create()

but it looks more "explicit" to have it in init method, thank you!

Thank you all, great job!
