Consider making fine-uploader a peer dependency

[rnicholus]

Instead of automatically installing fine-uploader, perhaps it should be a peer dependency. This may make more sense for projects that already install fine-uploader for use elsewhere in their app where react-fine-uploader is not being used. I can see some projects gradually moving their React-based upload widgets over to react-fine-uploader, and they probably would like to avoid having fine-uploader bundled twice. Not sure this is a valid concern yet - needs more exploration.

nah - not convinced there is any real benefit to making this a peerDependency

On second thought, maybe this is a good idea as it will make it easier to ensure only one copy of Fine Uploader exists, and put the responsibility/power on the integrator to choose the specific version of Fine Uploader to use. The wrappers project should be updated in this manner as well.
