Rustup Toolchain Install Master Versions Save

Now supports downloading the rust-src component.

• When an installation failed, this program will now immediately exit with error.
• Added -k (--keep-going) flag to restore the old behavior.

Added the -c (--component) flag to download additional components (#4).

• When no arguments are given, this tool will automatically fetch the latest master commit and download that (#2).
• Fixed cross-device rename error when /tmp and $RUSTUP_HOME are in different disks (#3).
• The progress bar now print to stderr instead of stdout.
• Added --dry-run and --github-token flags.
