Allows for per-buffer and global toggling of signs. WIP. The global toggle will override buffer local sign settings - if a buffer has signs disabled, but you globally toggle signs on, that will turn signs on for that buffer too.
Also allows sign toggles to work with bookmark signs.
@andrewferrier can you test this PR out? I don't use sign toggles at all, but maybe you can confirm that this at least fits in with your intended workflow.
