Use new dash-plugin URL scheme
Use system Ruby for bundle command.
Use ^h as shortcut for context-sensitive lookup.
Add docset mappings for Sass and SCSS.
Extract `scope_lang` as method.

We’ll need this later to fine-tune “current word” according to the scope language.
Extend “current word” for CSS to match full dash-separated properties.

Code taken from the CSS bundle’s “Documentation” command.
Extend “current word” for Ruby to include trailing ? and !.
Fix scope determination for scopes like `source.ruby.rails`.

Always using the second element of the splitted scope string should work fine for all cases.
Remove coffee, html and css docsets for JavaScript.
Add docset mapping for CoffeeScript.

Same as for JavaScript (but of course including `coffee`).
Fix language detection for `text.*` scopes (like HTML).

This is a bit tricky for PHP, though: In PHP documents both scopes, "text.html.php" and "source.php", are simultaneously active. So we have to make sure to prefer the "source.*" scope in such cases.
Remove CSS and JavaScript (+ JS-Frameworks) from HTML docset mapping.
Add docset mapping for Haml.
Add docset mapping for Slim.

Same as for HTML.
