Eclipse 2018-12 | .puml files not being read

[aaiezza]

This was working on Eclipse 2018-08 last I used it, however with the recent upgrade the plugin has been rendered broken when generating images for .puml files.

Source code generation for Java classes works great still. But now when a model gets rendered from the .puml syntax the following occurs:

This is a duplicate of issue #77. The problem is I used internal Eclipse API (shame on me) for supporting PlantUML diagrams for class files, and this breaks in later 2018 releases. I'm removing this feature to avoid the problem, and will release "soon".
