What kind of platforms have in file depencdencies?

I just checked the code and the platform option for file dependencies does not appear to actually be used. I think the documentation is wrong, so I removed the section referencing the platform. (It's still used for Cordova plugin dependencies though, this only applies to file dependencies.)

It strange because when I tried in r260 it worked with "nwjs" parameter.

In export only paste in nw.js export
