Provide a way to delete an installed version of KRE

[davidfowl]

For example I want to delete some old version of installed KRE, kvm should provide a way to delete them. Currently it is a manual folder delete.

This is similar to aspnet/dnx#319, but this item is to delete the KRE not the alias. By this we delete the KRE, but the alias still lives.

From aspnet/dnx#322

Should also delete related alias?

I don't think so ... An alias doesn't point to a particular installed version of KRE (e.g. KRE-svr50-x86.1.0.0), just the package version number (e.g. 1.0.0). We could delete the alias if all installed versions of that alias are deleted, however I imagine one use case might be to delete a .NET install (e.g. svr50) and then install the core runtime for the same version using the alais. e.g.

kvm uninstall myalias -svr50
kvm install myalias -svrc50

We probably also want to support a -all switch for deleting (uninstalling) all installed packages for a version or alias.

[graemechristie]

Additionally we may want to mandate that the user specifies runtime or architecture specifically on the command line when there is more than one architecture or runtime package installed. That is, if the user has both "svr50" and "svrc50" runtimes installed, they would need to specify -svr50, -svrc50 or -all on the command line explicitly.

Has this been added? I am currently on 1.0.0-beta4 - no uninstall command. I was unsure if it is safe to delete the run time folder but I'll be doing it anyway.

[muratg]

@xanather it's not added, and it should be safe to delete the runtime folder.

Closing this as #254 tracks the suggestion
