Avoid searching for old nightlies in missing dirs
These directories may be missing (e.g. a first time build or due to Buildbot cleaning),
so don't try to look inside them for old nightlies if so.
I noticed this in http://build.servo.org/builders/arm32/builds/6815/steps/shell__1/logs/stdio.

Add a new `-keep` flag to `./mach clean-nightlies` to control how many
nightlies to keep, which keeps the n most recent nightlies found in git.
Use this to clean old nightlies at the start of each build,
currently keeping 3 nightlies at a time.
- Default to interactive mode and remove the `--interactive` flag
- Use `--force` to skip interactivity
- Change MSVC dependency storage organization on disk: put each version
into its own folder and directly refer to the versioned folders,
providing immutability and making the installation list redundant
- Reuse `host_triple()` function to fix broken bootstrapper dispatching
- Simplify code:
- Remove or inline many unused and redudant functions and variables
- Prefer plain functions to classes
- Consolidate into fewer files, remove unnecessary bootstrapper/ dir
- Improve Python style
- Sort dependency list
Instead of once per day (or night) with a date in the URL,
Cargo binaries are now built and published for every merge to master
(with the merge commit hash in the URL).
- Add SERVO_USE_NIGHTLY_RUST env var to use the latest rust/cargo nightly snapshot
- Fix up looking for cargo binary (in cargo/bin/cargo, not bin/cargo)
- Fix up win32 executable checking (use .exe suffix)
- fix up win32 PATH handling (subprocess must use shell=True for PATH change to be honored)
Urg! The Chromium HSTS preload JSON file contains single line comments. Previously these were filtered out with a very simple regex that just looked for '//' and removed the line. Now the file has added a couple fields that have URLs in them that were erroneously removed and caused the JSON parsing to fail. This commit slightly complicates the regex to fix this specific problem.
If this happens again, it's likely worth it to figure out how to use a real parser to remove the comments.
