With this change MuranoPackage becomes first-class DSL citizen. Packages have version, runtime_version (that is specified in Format attribute of the manifest file) and a list of classes. Previously engine used to have package loader which had most of "load" functionality and class loader that mostly acted as an adapter from package loader to interface that DSL used to get classes. Now class loader is gone and is replaced with package loader at the DSL level. Package loader is responsible for loading packages by either package or class name (as it was before) plus semantic_version spec (for example ">=1.2,<2.0"). Package loader can now keep track of several versions of the same package. Also packages now have requirements with version specs. All class names that are encountered in application code are looked up within requirements only. As a consequence packages that use other packages without referencing them explicitly will become broken. An exception from this rule is core library which is referenced automatically.
