Replace alphabetical sorting by un-sorting

[kirillt]

Alphabetical ordering of links doesn't really look useful and should be removed. In its turn, having "unordered" list mode could be useful because it would not spend time on sorting links when user doesn't care about order, e.g. when they use search or filtering by tags.

How does this fit in with the current changes in the svelte feature branch? Alphabetical seems to be introduced in the latest commit?

@mberry yes, we should remove it from there.
