Improve tag-handling in the sidebar tags widget

[natrius]

It would be nice if there would be settings to

• sort tags in ascending order (currently alphabeetic)
• Limit shown tags with a "Show all"-Button below

Expanind hugo.toml with

[Params.widgets]
  ...
  tags_counter = true # Enable counter for each tag in "Tags" widget
  tags_sort_by_counter = true # Sorting by the amount the tag is used. Use false for alphabetical.
  tags_limit_shown = 0 # 0 for all, integer for the amount of tags be shown in the sidebar

could be used for this.
