updates for dart runtime 1.6
update test projects and cinderblock.xml for new single-lib layout
load cinder.dart up front, it has to in order to swap in print handler, and this way the user doesn’t have to import ‘cinder’ unless they want to use functionality from it.
use the new toDart() to create dart string
removed dart-runtime submodule
added dart runtime headers and readme
initial check in of fetch libs script
updated readme
minor format improvement for profile logging
renamed fetch libs script to make it clearer that it only runs on mac
remove empty .gitmodules file
use ‘cinder.dart’ for includes to match other include schemes
Merge pull request #3 from richardeakin/runtime-1.6_no_submodule

update to runtime v1.6.1, remove submodule in favor of script
