Merge branch 'UsingBasicIceSeq' into 'master'

replaced user defined sequences of basic types with ice sequence types

replaced user defined sequences of basic types with sequence types provided by ice (if the user defined sequences did not offer any more syntax
e.g. armarx::StringList was replaced with Ice::StringSeq
a type like 'sequence<string> ObjectNames' offers more syntax and was not replaced
