Removing execSync

[eddiemoore]

Removing execSync and making codecov-node require node version 0.12+. This SHOULD make codecov work on node v7

Removed node v0.10 and v0.11 from travis.yml and added v7

Updated version number to 2.0.0 since it will no longer work on node v0.10

Had to comment out one test for now as i'm not quite sure what it is meant to be doing, however it always fails.
