Extracted App::MojoSlides::MoreTagHelpers => Mojolicious::Plugin::MostTagHelpers

Hi Joel,
Last weekend I've created Mojolicious::Plugin::MostTagHelpers.
Mojolicious::Plugin::MoreTagHelpers namespace was already in use.
Now I adapted App::MojoSlides to this.
You only need to update the changelog and bump up the version.
I plan to do some things in MostTagHelpers with HTML::Tagset asap.

Wish you and your family a merry christmas.

Best regards from Dresden
