Composer: Run Script - Auto-detect defined scripts

[kAlvaro]

The Composer: Run Script works flawlessly but you need to type the script name every time. It'd be nice if it could auto-detect available scripts and either expose them as commands:

Composer: Run Script → start Composer: Run Script → build Composer: Run Script → …

… or feed them to some drop-down list or auto-completion thingie.

You can get a script list with composer run-script --list or parsing composer.json.

Anyone interested in picking this up for development?
