This commit reimplements the private RestartFileView class in terms of the ERst class. The latter supports all operations we currently need, although we can no longer use a 'const' object since loading arrays mutates the ERst instance. Most changes here are fairly mechanic and most of the new complexity concerns how to identify a vector (keyword) of a particular element type. We make special concessions for INTEHEAD, since this vector plays a central role in accessing the other data vectors. The mutability of RestartFileView is underscored by using shared_ptr<> in the various helper facilities.
