Promote v1 branch to default on github, or FF into master

[jonjaques]

Hello,

Since npm i -S redux-async-connect will install 1.0.0-rc4, I think it follows that either the v1 branch should be the default here, or we should just FF master.

I see a few issues that seem to be related to version/docs mismatch and I think you would see less of them if that distinction were clear. I ran into this issue myself, so at the very least a note on #master readme would be good. 😄

Looks like #66 and #58 are results of the issue described.
