Bugfix: InspectingContent flag

When an empty array of content types was set (as is default through the UI), the 'Inspect content' checkbox was being automatically set. Now this only happens if the array is not empty.

This behaviour is so that declarative pipelines can declare content types but not have to explicitly set the flag.

Pipeline compatibility update

Updates to support pipeline jobs and declarative syntax. Syntax examples can be found in the main README document.

Requires:

• Java 1.8
• Jenkins 2.176

Fixed a null pointer bug when running against old config
