Drop support for Julia v0.6/v0.7 (#130)

* REF: Remove support for Julia < v1.0

changes to use `import` instead of `using`

removes all reverse compatibility code for julia versions lower than v1.0

adds unit testing on julia 1.1 and nightly (allowed failure)

removes compat (no longer required)

* FIX: dss parse logic

* FIX: failing multinetwork test

* FIX: ACR formulation

Updates the new ACR formulation code to be compatible with Jula >= 1.0 syntax

* UPD: transformers feature

* ADD: Project.toml

* UPD: Travis tests

* REF: project.toml

comment out `compat` entries for test packages, remove MOI from `deps`
