Feature/user token replacement

I need a simple user token replacement:
- added new argument "ut=|usertokens="
- receive a path to a file which content follow the syntax:
```
UserId=123
UserName=Some Name
```
- parse the file content to a Dictionary<string, string> into ConfigurationPropertyHolder.UserTokens
- when creating a dictionary from configuration in TokenReplacer.create_dictionary_from_configuration, check for the property UserTokens and add all properties to the final dictionary

I couldn't be able to run my new tests through test.bat. Is there any place explaining how to add more unit tests?
