Updating react dependency

There is a mismatch of dependencies between what you declare as the minimum version of react/socket and what cboden/Ratchet declares starting in v0.3.1 of the Ratchet repository (they are currently now on v0.3.2, with working being done towards v0.4).  This caused issues with conflicting dependencies when trying to install the latest versions.  

The way I see it, there's 3 options to fix it: Either fixing this package to depend on v0.3.0 of Ratchet and no others (not optimal), changing the react dependency to match Ratchet's (which is what I've done here) or completely removing the react dependency and letting Ratchet stipulate it.
