Rustfmt nightly

[imp]

This PR enables running newish rustfmt tool (known as rustfmt-nightly).
Its version numbering scheme has been restarted from 0.1.0.
To whitelist these new builds, the version regex was changed to only trigger when the version numbers are NOT followed by -nightly suffix.

See #358

Check all those that are applicable and complete.

• Merged with latest master branch
• Regenerate documentation with npm run docs
• Add change details to CHANGELOG.md under "Next" section
• Added examples for testing to examples/ directory
• Travis CI passes (Mac support)
• AppVeyor passes (Windows support)

This is great so far!

Would you be interested in converting the existing Rustfmt beautifier over to using Beautifier Executables? "Executables" standardizes usage, error handling, and generated documentation.

Examples:

• See Add goimports beautifier for Go language #1726 for an example Pull Request implementing an Atom-Beautify "Executable".
• https://github.com/Glavin001/atom-beautify/blob/master/src/beautifiers/autopep8.coffee#L12-L42 and https://github.com/Glavin001/atom-beautify/blob/master/src/beautifiers/autopep8.coffee#L49

By using "Executables" you could check version with rustfmt.isVersion(YOUR_VERSION). See

atom-beautify/src/beautifiers/php-cs-fixer.coffee

Line 75 in 5f968cb

isVersion1 = ((phpCsFixer.isInstalled and phpCsFixer.isVersion('1.x')) or \

for example.

I would love to have a look. Cannot promise I'll have enough free cycles to implement it though.

[Glavin001]

No worries, @imp. How about I merge this as is and if you have time it would be awesome to have another Pull Request bringing Rustfmt up to speed using the new Executables feature in Atom-Beautify. Thanks for contributing!
