Cleanup of project settings as triggered by
Bug 316553  -  [compiler] Interactive export of OT-plugin does not use compiler preferences
- enable passing compiler settings to export/build by setting javacProjectSettings=true
- reduce arbitrary setting of project specific settings, except for:
  + binding_conventions, inferred_callout
- but set/keep org.eclipse.jdt.core.compiler.problem.indirectStaticAccess when
  using javacProjectSettings as a workaround to avoid warning re build.properties.
- more cleanup in some build.properties files.
