Bug 546282 - [ui] Implement "organize imports"v_3.0.2
Implemented a fairly general mechanism that can be adapted easily for other models, e.g. one using the FSM part only. Conflicts: plugins/org.eclipse.etrice.core.common.ui/src/org/eclipse/etrice/core/common/ui/imports/ImportOrganizer.java Change-Id: If6f6d6039833c2e54a337b60d41be6bb20b0ed0a
