make assertion labels unique already when loading a verification condition,
keep abstract view on verification conditions and provide various splitting operations on verification conditions,
allow to discharge only parts of a verification condition,
extended the command "boogie_vc" with options to consider only some assertions or to split a verification condition into its paths,
added a narrowing option to "boogie_status" (a divide-and-conquer approach for identifying the "hard" subset of assertions of a verification conditions),
added tactics "boogie", "boogie_all" and "boogie_cases",
dropped tactic "split_vc",
split example Boogie_Max into Boogie_Max (proof based on SMT) and Boogie_Max_Stepwise (proof based on metis and auto with documentation of the available Boogie commands),
dropped (mostly unused) abbreviations
