4 new features

• New: migration step file/prepend, works just like file/append but adds content at beginning instead of end of file

• New: migration steps file/append, file/prepend and file/save can load the file contents from a template file on disk besides having it inline in the migration definition

• New: all migration steps that deal with the content repository, as well as sql, php class, sf services, files, mail,http calls, process execution have gained support for being skipped via an if tag. The semantics are the same as for the existing step migration/cancel:

  if: # Optional. If set, the migration step will be skipped when the condition is matched
      "reference:_ref_name": # name of a reference to be used for the test
          _operator_: value # allowed operators: eq, gt, gte, lt, lte, ne, count, length, regexp
  

• New: it is now possible to define the following parameters using siteaccess-aware configuration:

  kaliop_bundle_migration.version_directory, ez_migration_bundle.table_name, ez_migration_bundle.context_table_name

  This is useful when you have multi-site eZPlatform installations which do not share a single Repository database, and as such might need to execute different sets of migrations for each site.

  As an example, just use this parameter format: kaliop_bundle_migration.my_siteaccess_group.version_directory
