Just a tiny bit different from gaia-7001, the gaia-7001a

While we are waiting for gaia-7002, some validators would like to make gaia-7001 keep running and continue to have some tests. Some of us decided to start a new small chain. We collected some genesis tx from some validators and started the gaia-7001a with a small fix committed by @slamper which make block sync faster. Any validators are welcome to join this chain if you would like to have some tests with gaia. Please visit https://github.com/forbole/gaia-7001a and checkout the correct commit c01a3d218f2544b00b817942e996e171c397b2a4. Then you can start connecting to gaia-7001a with the genesis.json in the repo.
