chore(npm): add shrinkwrap to lock down dependencies

We need to be able to build angular at older shas, without the lock file / shrinkwrap file
the dependencies will resolve differently on different machines and at different times.

This will help us avoid broken builds and hard to track down issues.

I had to manually edit this file after it was generated because `npm shrinkwrap` will install
optional dependencies as if they were hard dependencies.

See: https://github.com/npm/npm/issues/2679#issuecomment-37361236

My manual edit:

```

```

Additionally chokidar doesn't list the dependencies above as optional, but that will hopefully
be soon fixed: https://github.com/paulmillr/chokidar/pull/106

In the meantime the patch from the PR above needs to be applied to
node_modules/karma/node_modules/chokidar/package.json before running `npm shrinkwrap`

----

After this change is applied, angular core developers don't need to do anything differently,
except when updating dependencies we need to call `npm update && npm shrinkwrap --dev`
followed by reappling my patch above until npm's bug.

Closes #6653
chore(version-info): better error msg if not tags
chore(version-info): use remote tags and increment patch version
chore(shrinkwrap): re-run shrinkwrap locally

This will make the following commit clearer when the update is run.
chore(shrinkwrap): update dgeni-packages
chore(CHANGELOG.md): add input type date PR as breaking change

fix($http): don't covert 0 status codes to 404 for non-file protocols

PR #5547 introduced conversion of all 0 status codes to 404 for cases
where no response was recieved (previously this was done for the
file:// protocol only). But this mechanism is too eager and
masks legitimate cases where status 0 should be returned. This commits
reverts to the previous mechanism of handling 0 status code for the
file:// protocol (converting 0 to 404) while retaining the returned
status code 0 for all the protocols other than file://
