DotMake.CommandLine v1.7.2

• Added advanced validation. In [CliOption] and [CliArgument] attributes, removed AllowExisting property and added ValidationRules, ValidationPattern, ValidationMessage properties.
  ValidationRules property allows setting predefined validation rules such as ExistingFile, NonExistingFile, ExistingDirectory,
  NonExistingDirectory, ExistingFileOrDirectory, NonExistingFileOrDirectory, LegalPath, LegalFileName, LegalUri, LegalUrl.
  Validation rules can be combined.
  ValidationPattern property allows setting a regular expression pattern for custom validation,
  and ValidationMessage property allows setting a custom error message to show when ValidationPattern does not match.
