Adding Screenshots to failing steps

These only appear when they have been embedded in the report json.
I've also removed commented-out code.
Removed <pluginManagement /> so that Travis CI can pick up the required Java version
Set maven-compiler-plugin version to 2.5.1
Moved the compiler plugin configuration outside of the profile so it actually gets picked up
ReportParser now stores featureResults using a LinkedHashMap rather than HashMap; Maintaining the order of inertion should prevent unit tests from failing randomly
Fixed formatting
