Default to use localipfs

[victorb]

Doesn't work because it's trying to find a plugin named "" (I'm guessing)

➜  iptb git:(master) ✗ iptb auto
testbed nodes already exist, overwrite? [y/n]
y
Could not find plugin

While this does work:

➜  iptb git:(master) ✗ ./iptb auto -type localipfs
testbed nodes already exist, overwrite? [y/n]
y
node[0] exit 0

to get started, enter:

        ipfs cat /ipfs/QmS4ustL54uo8FzR9455qaxZwuMiUhyvMcX9Ba8nUH4uVv/readme

Or add some config/environment variable to set this default.
