This review includes - source code changes to port Serilog to support
ASP.NET vNext (includes support for console, file, system.diagnostics to
start with), smoke test updates. This also includes a temporary Demo
project to show all the above features working on vNext. The
Serilog.vs2015 solution is created SxS which includes the new projects as
well so that people can still open the original solution without issues on
VS 2013.
Merge branch 'master' of https://github.com/kanchanm/serilog into kanchanm-master

Conflicts:
	src/Serilog.FullNetFx/Properties/AssemblyInfo.cs
Removed the "Demo" project, since SmokeTest has this covered.
Merge branch 'kanchanm-master' into dev
