Merge pull request #210 from Icinga:fix/escape_strings_in_array_dsl_properly

Fixes DSL for building array elements escaped

Updates the Icinga DSL for building PowerShell arrays to ensure all string values are properly escaped with `'`. In case the user already wrapped commands with `'` by himself, this will not have an effect as we only add single quotes for escaping if they are not present already.
