Subject: [PATCH] fixed https://github.com/ethercreative/tags/issues/21 and
 https://github.com/ethercreative/tags/issues/18

for custom element types, Craft manages and invalidates element index cache on adding or editing an element. but for tag element, when you add or edit a tag via element index page or even tag field on entry page, Craft is not aware of this plugin's tag element type so this PR invalidate element type cache for this plugin on after save tag event
