Multi-root support, lint support, DocumentSymbol support, and more!

[wingrunr21]

Quick feature overview:

• Adds multi-root support
• Adds diagnostics support (eg lint) with rubocop, reek, and standard
• Formatting support (both document and selection) for rubocop, standard, and rufo
• Adds considerably better folding range support <add before/after here>
• Adds DocumentSymbol support which enables the Outline view
• Adds out of the box environment detection for RVM, rbenv, chruby, etc environments. If your login shell sets things up correctly, VSCode should set things up correctly

I will be writing up some docs + a few additional cleanup items and will release this as 0.22.0 tonight/tomorrow

@wingrunr21 I would like to inquire about whether this should be considered version 1.0.0.instead of another prerelease version bump. This is a significant rewrite of a majority of this application. Also, assuming vscode-ruby follows semver, anything before 1.0.0 is considered prereleased; this extension has been publicly released for a while now.

[wingrunr21]

It will be released as 0.22.0.

• VSCode does not have the ability to do pre-release extensions. The only way for an extension to be used is for users do to manual installation or to not really follow semver.
• This is a major rewrite of things and I expect there to be bugs. I'd like to issue patch-level releases on that version number.
• There's a good chunk of the extension that doesn't work correctly (like debugging)
• This is technically backwards-compatible. I tried to make extension settings compatible with today's settings. Over time, I'd like to optimize these settings a bit more but right now I went for compatibility.

I'd like to release v1 when the extension is in a good place. This is a major step in that direction but it isn't there yet.

[ecbrodie]

Okay fair enough, I respect that.

Should it be possible to have a .rubcop.yml in a sub-directory and have VSCode automatically detect it? Are path entries (e.g. ignores) relative to this file? I guess I'm missing something?

[wingrunr21]

Everything is run with a cwd of the workspace root and/or the file's directory for single files. This would be the same behavior as running RuboCop from the root of your Rails app. Otherwise everything is done via RuboCop itself.

The extension only passes configuration to RuboCop via command line arguments. Otherwise, anything specific via .rubocop.yml or other config files are handled by RuboCop.
