Add .fengniaoignore file to auto-exclude files upon running

[Makazone]

Currently, you have to supply exclude paths via inline arguments fengniao --exclude Pods. However, in situations when your app displays assets based on image names returned by API you will want to exclude a lot of files/paths.

It will be handy to have an .ignore like file similar to .gitignore so that each time I run fengniao I won't need to remember which files I need to exclude.

This file could be called .fengniaoignore and be structured similarly to .gitignore.

Let me know what you think about it and I can make a PR for it.

Thanks for the handy utility!

Hey, thanks for the suggestion.

Currently you could just write a simple shell script for it. However, I agree with you that there could be a better way.

Instead of a .ignore file, I believe it would be better if we could have something like a "config" file, and then pass it as a config option to the command line. Maybe something like this when using:

fengniao --configuration fengniao.json

By doing so, beside of the exclude paths, we could also pass other parameters from the file and make things easier.

Sure, a p-r is warmly welcome for it, even you'd only implement the "exclude" part (and I could do other parts of it later). If you think it's better to have a standalone ignore file, please also let me know and we could have more discuss on it! :)

Thank you.
