added: Custom data types
 - It is now possible to define custom types of arguments (eg. to import
custom classes / interfaces ad create instances of them). It is necesary
that those classes are availabel in the time of loading the scenario
file, because the instances are created at that time.
 - sample of usage is in "Sample scenarios\player_scenario.xml"
 - custom datatypes are only available in UniPlayer, UniMocker will
follow

added: NoSuchBundleException
 - EnvProbe now throws NoSuchBundleException when trying to find
non-existing bundle.
added: Custom types support for UniMocker
 - It is now possible to use custom data types in UniMocker scenarios.
 - sample in "Sample scenarios\mocker_scenario.xml"
added: settings element in UniMocker scenarios for custom data types
definition
fixed: forgoten namespaces
