v1.0.0-beta.0

This is the first beta release of the v1.x series of this addon. It's had a huge upgrade to Ember/EmberCLI 3.11 and has had most of the dependencies updates. (the LD client JS has not been brought up to date as yet, but this will come in beta.1).

Other than upgrading the LD client js, there are no other changes planned before moving to v1.0.0 and so this is pretty much good to go. Just released it as a beta in order to ensure everything still works.

This release includes the following:

• [BREAKING] Make babel transform (for enabling the variation JS helper) opt-in #30
• [BUGFIX] Lazy lookup LD service in window.ld global #31
• Upgrade to Ember 3.11 (see PR description for details) #33
• Reimagine how the babel transform works (see PR description for details) #53
• Upgrade to ldclient-js 1.7.4 #28
• Various dependency upgrades
