Feature: ignore-exclude

[Ciantic]

I have this kind of directory structure:

manifest.json
background.html
...
plugin/... visual studio files
plugin/Release/... visual studio files
plugin/Release/np_myplugin.dll

I would like to include everything from root, and only plugin/Release/np_myplugin.dll but I cannot ignore the plugin or Release directories because np_myplugin.dll would be ignored, so it would be handy to have some kind of ignore-exclude switch to reversing some ignore parts.
