From 0601ed29d91b0786fc42b772087cb8421777e5e3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] 1. Added a way to check if the genesis block is ready in
 chainActive before sending the ready event. We think that once chainActive[0]
 is not returning NULL, we should be ready to query the local blockchain. 2.
 Added the env variable BITCOINDJS_DIR support in the integration tests.
