chore(travis): blacklist Dart SDK 1.7.0-dev.2.0

1.7.0-dev.2.0 fixed a bug in 1.7.0-dev.1.0 but it's causing other
failures.  So now we have both versions blacklisted and will be using
1.7.0-dev.0.1 for the dev channel tests.
style(protractor): fix indentation and style in config files
chore(travis.yml): minor indentation fix
test(e2e): use DARTIUM_BIN instead of DARTIUM

This is in line with karma.conf.js.

fix(resource_url_resolver): fix DOM parsing for Safari

Closes #1439
fix(resource_url_resolver): correct type for Node
fix(bind-*): zone.run scope.apply on bind- change events

Due to dart bug, events registered with addEventListener do no fire
scope.apply().

Adds an example of an affected polymer component.
chore(sauce): increase timeouts to avoids disconnects

e.g. See disconnects for job https://travis-ci.org/vsavkin/angular.dart/jobs/35114674#L1272
test(e2e): run on Dartium, dart2js and sauce browsers

Command line runs will test Dartium by default if no BROWSERS are
specified.  If BROWSERS are specified, they all have to be local
browsers or all sauce browsers.  If you're only specifying sauce
browsers (e.g. SL_Chrome, SL_Firefox, etc.), you may optionally also
specify DartiumWithWebPlatform and this will run two instances of
Protractor.  (This is a limitation of Protractor's config.)

On Travis, the job for a specific SDK version tests both
DartiumWithWebPlatform as well as SL_Chrome.  SL_Firefox is currently
disabled because it's failing.  Note that prior to this commit, the
BROWSERS variable was always ignored.
