Add ruleset @name to example file
Add versions to messages (prolly too late)
Differentiate between style and options lists

They expect different values, as raised by #2. See also:
https://www.sublimetext.com/forum/viewtopic.php?f=2&t=3007#p14196

(To my knowledge "underline" is not supported in "fontStyle".)
Allow `"fontStyle": none;` for empty style list

Will be translated to `<key>fontStyle</key><string></string>` and is not
allowed with other styles.

Closes #4.
Highlight SASS's `index` function
Actually show a message if original line not found
Increase amount of lines to crawl for line numbers

10 is not that much.
Add @each usage to the example file
my_sublime_lib: Allow `OutputPanel().write_line()`
Update syntax definitions to (style) list changes
Push new snippets after SaneSnippets changes

Also add newlines at the end of sane-snippet files because I forgot to
set that setting earlier.
Highlight `from` in @for as keyword.control
Add a bunch of new snippets
Update README to today's changes
Allow 'underline' for style lists again

I guess TextMate interprets this so we shouldn't disallow it.
