Update to .NET Core RTM

[adamsitnik]

FYI I am working on that, will update nuget packages and drop dnxcore50/dnx451 support.

Ok, it's done.

@mattwarren @AndreyAkinshin @ig-sinicyn You need to upgrade your tools, full description here

Breaking change:

• I have dropped dnx451 and dnxcore50 support. (nobody should use it anymore)
• We will no longer need separate nuget package because of the beta dependencies

When will it be on nuget?

When will it be on nuget?

@niemyjski only @AndreyAkinshin can tell ;)

[AndreyAkinshin]

As soon as possible. I still have some troubles with the roslyn toolchain. =( Hopefully, end of this week.
