Consider using ^ instead of ~ for dependencies #139
Description
At the moment, v1 of react-svg-loader is forcing installation of old versions of dependencies like babel-core. It would probably be save to use ^ instead of ~ for those so that we don't have to install old versions alongside our newer versions. It looks like you're using greenkeeper to keep things up to date, but that requires releasing a new versions every time...
At the end of the day, it's not a huge deal as those libraries don't typically end up in client side bundles, but it varies from other projects. You may have a very good reason for doing this, in which case feel free to close this out. Thanks much for this loader, it's helped us a lot!
