Test suite using multiple Minecraft server versions

[deathcap]

Would be nifty to have an automated test suite, running on CircleCI or TravisCI, using https://github.com/rom1504/node-minecraft-wrap to download a bunch of Minecraft versions and ping each of them. Could test all the way back to 1.2.5 (no earlier yet PrismarineJS/node-minecraft-wrap#9), and perhaps even every single release version after then, or at least the major versions:

• 1.2.5
• 1.3.2
• 1.4.7
• 1.5.2
• 1.6.4
• 1.7.10
• 1.8.9
• 1.9 snapshot(s)
• Glowstone++ open source server https://github.com/GlowstonePlusPlus/GlowstonePlusPlus
• Cuberite open source server https://github.com/cuberite/cuberite
• flying-squid open source server https://github.com/PrismarineJS/flying-squid
• other servers?
