use HashStringList in the acquire system
It is not very extensible to have the supported Hashes hardcoded everywhere and especially if it is part of virtual method names. It is also possible that a method does not support the 'best' hash (yet), so we might end up not being able to verify a file even though we have a common subset of supported hashes. And those are just two of the cases in which it is handy to have a more dynamic selection. The downside is that this is a MAJOR API break, but the HashStringList has a string constructor for compatibility, so with a bit of luck the few frontends playing with the acquire system directly are okay.
