* remove invalid tycho resolver config (not valid since many versions)
* fix PMD plugin configuration (config attribute was renamed in 3.18)
* remove duplicate versions already managed in pluginManagement section
* fix indentation
* move all not yet configured versions into pluginManagement of the
parent module to avoid further duplication
* consume the target platform as file, not as maven artifact (this
simplifies building a single module A LOT)
* remove invalid tycho-source-plugin configuration
* disable tycho consumer POM generation (not needed here, and avoids a
warning in each module)
* remove prerequisites. that's for maven plugins only, and this POM
already contains the better suited similar maven enforcer rule
* enforce UTF-8 for javadoc generation (the build fails on Windows
otherwise, trying to read some Japanese? characters with the Windows
default encoding)
Some bundles are bumped because dev happened between 11.2 release and
this version bump. The most significant change that happened
was the bump in Tycho version which changed ECJ version and
hence some class files changed
