AqBanking

- fixed progress bar: Now show the correct percentage (but for HBCI only at
the end, I will have to change the result transfer code in AqHBCI to
change the status of AqBanking jobs earlier)
- marked queue execution functions which do not take an importer context
as deprecated: They are still supported for a transitional period but
applications should use those functions which do take a context.

This is necessary because otherwise we would loose data from some backends
  (e.g. yellownet, see below).

By the same token, functions which return response data stored in jobs (like
  AB_JobGetTransactions_GetTransactions) are also marked as deprecated.
  This is to avoid having two different methods for backends and applications
  for importing response data.

Backends store all responses in the given AB_IMEXPORTER_CONTEXT from which
  the application can take them. This way AqBanking can make sure that the
  application will get even data which it did not request explicitly.

The reason for this decision is that some backends do not allow to select
  for which account statements are to be retrieved. Those backends rather
  return all data for a given user (e.g. statements for all accounts of a
  user at a given credit institute).
  With the previous method of storing responses directly within the job
  objects any additionally received data will get lost, and even worse,
  some backends allow the server to remove data it has already sent, so this
  data will be lost for good.
  We can't allow that to happen within AqBanking. Applications may choose
  to ignore this additional data, but AqBanking will not.

The new approach obsoletes the function AB_Banking_GatherResponses so it has
  been marked as deprecated, too.

QBankManager, KMyMoney, Grisbi and all other programs which use the
  frontends provided by AqBanking will work with these changes without
  changes.

Gnucash will show 3 compiler warnings about using deprecated functions,
  but it will still work with these changes.

These changes make it necessary for every application to be recompiled
  because the major SO version number must be changed for AqBanking 2.0
  (SO_AGE->0 because of incompatible API change) and I don't want to increment
  the SO-VERSION before a release.
