* Add forgotten --eol argument to 'git ls-files'. Without it, in certain
  edge cases, files might have their mtime restored when it shouldn't.
* Don't parse ls-files output into fields; it's unnecessary.
* Disable the pip cache dir, and stop saving it to the appveyor cache.
* Leverage the 'git -C «dir»' flag to make a script shorter.
* Fix some factually and/or grammatically incorrect comments.

- Adding a ModuleId type alias to specify original url or local file of

1. This allows the installer to use a more aggressive CI build matrix
   with different version of python.

2. Running the installer during tools/test.py artificially inflates our
   download stats.

3. Running the installer during tools/test.py makes the test script
   dependent on having an internet connection.

4. Running the installer during tools/test.py introduces a race
   condition during release - where it tries and fails to download the
   latest release in build process that should be uploading that release.

* Fixes module resolution error #645
* Better flag parsing
* lStatSync -> lstatSync
* Added deno.renameSync()
* Added deno.mkdirSync()
* Fix circular dependencies #653
* Added deno.env() and --allow-env

This fixes that a lot of targets were being rebuilt unnecessarily.

Fixes #677

Windows can't handle ":" in path names, so we use a special directory
format .deno/deps/localhost_PORT4545/ to represent hosts with
non-default ports.

Fixes #645.

Also removes assignCmdId as it's currently unused.

* Added https import support.
* Added deno.makeTempDirSync().
* Added deno.lstatSync() and deno.statSync().

Adds hyper-rustls to the build.

Use ring for sha1 instead of "ssh1" crate.
