Update package versions and clean up code

- Bump `UserManager` package to version `1.1.1` in
  `EnvelopeGenerator.Application.csproj` and
  `EnvelopeGenerator.Infrastructure.csproj`.
- Add reference to `DigitalData.UserManager.Domain` version
  `3.2.1.0` and `System.ComponentModel.Annotations` version
  `4.7.0` in `EnvelopeGenerator.CommonServices.vbproj`.
- Add reference to `System.Drawing.Common` version `4.7.3`
  in `EnvelopeGenerator.CommonServices.vbproj`.
- Update `UserManager.Domain` package to version `3.2.1`
  in `EnvelopeGenerator.Domain.csproj`.
- Remove unused properties from `EGUser` class in
  `EGUser.cs`.
- Mark `EnvelopeReceiverRepository` as obsolete, suggesting
  to use `Repository` instead.
- Update `packages.config` to include new package versions.
