Add testing of existence character "\n" (newline) in sshkey modules

- if some sshkey contains newline, throw exception now
- for sshPublicKey and sshPublicAdminKey modules
Add afs_group to changelog and fix filtering

- version 0.0.71, stable, low
- filtering also for usersFromPerun not only afs users
NOTIFICATIONS: fixed spring context for tests

- Fixed spring context to load proper *.properties file.
- It probably can be much better optimized in future.
- Tests still don't work, since DB schema used by code changed,
  but test-schema in *.sql files is unchanged.
SERVICES: ldap service manages also baseDN entry

- Manage also baseDN entry to prevent error in slave script
  which tried to add/or delete such entry.
- Updated script version.
REGISTRAR: fixed workflow with group applications

- If user not set on application to group, we still can search for
  user by actor/extSource to match users which joined identities after
  application submission.

Fix of setting large value into entityless attribute
Fix version of DB and remove password from GIT
Changes from engine-new:
   * recognize new db type (hsqldb) and fix syntax of some SQL commands
       - includes modification of hierarchical group name queries
   * allow for running tests without any external configuration files
     (inject properties from Spring, use default configuration)
   * add propagationType member to Destination class
       - values: PARALLEL, SERIAL
       - indicates desired mode of propagation (to all PARALLEL Destinations simultaneously, to one SERIAL Destination)
implement ExecService dependency scopes (SERIAL or PARALLEL) indicating desired behaviour for propagation
add methods for listing tasks together with engine id's and for inserting already existing task (with given id) into database
add property to ignore unresolvable property sources
use different method for determining DataSource database type, one that does not require a connection
read Destination propagationType from database

Conflicts:

fix bean configuration (use ignoreUnresolvablePlaceholders at the proper place), thanks to Michal S.
do not use "as" in join query to name the resulting table; Oracle does not like it and PG and HSQLDB do not mind
move column propagation_type from table destinations to table facility_service_destinations, as this is where it semantically belongs
add methods for listing tasks together with engine id's and for inserting already existing task (with given id) into database
avoid leaking open connection
add property to ignore unresolvable property sources
