- hits all of the checkboxes in #272
Specify test runtime explicitly and support testing w/ DNX Core on Linux
- turn on DNX Core on Linux testing with `--test-dnxcore` target
- or `KOREBUILD_TEST_DNXCORE` environment variable
Work around aspnet/dnx#2566
- builds fail with DNX Core on Linux otherwise
Do not attempt to install nodejs if not on Windows
Use user's `default` DNVM when `%SKIP_DNX_INSTALL%` defined on Windows
- enables builds with DNX Core
- should be the default for new repos; older repos can opt in
Use consistent case for all `--quiet` environment variables
- also name these variables consistently; start w/ `KOREBUILD_`
- environment variables are case-sensitive on Linux and mixed case was annoying
- also get rid of leading space in these environment variable values
Check `IsLinux` and not `IsMono`
- `IsMono` is always `true` on Linux since Sake always runs in Mono there
- but `IsLinux` is the right question
nits:
- remove tabs from a few files
- remove compilation warnings in local `makefile.shade`
