d11n 2e6246e385 Move TagHelpers to Abstractions (#3975)
* Move TagHelpers to Abstractions

Makes them available for use in plugins. Also cleans up the tag helper references in the view code: As we have it in the root view imports, the individual directives in the views are superfluous.

* Move CurrenciesSuggestionsTagHelper back

To get rid of the Rating dependency in Abstractions.
