fixes#11 (constructor and typed field semantics)
fixes#42 (Should we infer class property types from ctor args ?)
fixes#17 (number (js) should map to num (dart))
Closes#45
* remove `wraps` syntax enhancements for imports
and support new `import * as module from ...` syntax
- default imports are the wrong construct for importing
everything from a module
* moved tests from transpiler to jasmine and karma
- transpiler tests are included when running karma in main project folder
- transpiler is reloaded after every test run in karma,
so no need to restart karma when the transpiler has been changed.
- removed own gulp build for transpiler and `postinstall.sh`
as they are no more needed.
- transpiler tests are now executed in Dart AND JavaScript (used to be executed
only in Dart), which allowed to catch some bugs (see the bug with the
import specification above).
* made tests work in dart as well by using the following hack:
- dependencies are loaded from the `build` folder, which makes
running `gulp build` necessary before running karma for dart
- for this to work,
the dependencies are included in main `pubspec.yaml` of project
- reason for the hack: `karma-dart` loads all `packages` urls
directly from disc (should rather use the karma file list)
* added explicit annotations `FIELD`, `ABSTRACT`, ... to `facade/lang.*`
- needed for now that we can run tests and don't get errors for undefined
annotations.
* added `README.md` with details about the build and tests
