Inline mode needs a lot of new classes to be created. Please make PR if you wish to help.

Project converted to Visual Studio 2015 and new project type (xproj).

New demo console app added (TelegramBotDemo-vNext) for testing under dnx451 runtime. Old demo app ('classic' console project) also available, but Attention! Now it grabs package from nuget! (because old-style .csproj can't reference new .xproj assemblies directly).
