* add the Aes128 and Aes256 profiles
* Aes profies were tested on IoP workshop against Ascolab, Softing, Matrikon, Milo, ProSys and others
* Pss padding is not supported on all platforms, so autodetect if it is supported and filter out Aes256 if not
* not a breaking change: not specifying the SecurityProfileUri in the config xml will automatically add all supported profiles but not deprecated profiles (e.g. Basic256Sha256, Aes128, Aes256). Aes256 is only added if the platform supports Pss padding. This will simplify the maintenance of config xml, since automatically all supported and secure profiles are exposed.
- best possible fix for #189 to reenable https servers
- `UA Sample Client` and `UA Sample Server` expose https server. libuv.dll is by default for x64. Change
```
<PropertyGroup>
<RuntimeIdentifier>win7-x64</RuntimeIdentifier>
<BaseNuGetRuntimeIdentifier>win7-x64</BaseNuGetRuntimeIdentifier>
</PropertyGroup>
```
to win7-x86 if required.
- fix exception in https client when setting the Timeout
- fix travis build script for linux. kestrel server on ubuntu doesn't respond on ipv6Any ipaddress.
- fix a timing problem in the travis script.
2. Removed client cert validation from HTTPS client and server as this is not supported on all platforms, e.g. .Net4.6.
3. Reverted back to XmlDocument from XDocument as this is now supported via a NuGet package on UWP and XDocument is not supported on .Net4.6.
4. Baseline .Net4.6 samples and assoc. controls project check-in, not working yet.
5. Moved UWP client controls from SDK to Samples directly.
