[haxcms] replace-tag injection prototype

[btopro]

working on a prototype of haxcms's site builder actually forcing a rewrite at run time via regex. Things to clean up in this though it is working it would appear:

• [x] multiple - in name of tag support
• [x] support for blank / no loading message
• [x] look into speeding up things to instantly replace stuff already defined (could do this in constructor when with attribute detected)
• [x] nicer loading replacement animation, especially on scroll (pulsate maybe)
• [x] Support import only methodology where we ONLY import the item and disappear
• [x] ensure all other tags update when definition loads (promise ensures this with whenDefined)
• [x] do a build and ensure this works without issues there
• [x] start putting these into other themes and then add replace-tag as a requirement in the theme layer to ensure no misses in transition to this approach in endpoints
• [x] test in HAXcms WITH the authoring system loading in as well
• [x] clean up the API so simplify integration / payload
• [x] with, with-method, import, loading-text ; need to clean these up / ensure semantic as possible before mass roll out
• [x] write a lot of blog posts / videos about this cause it's really powerful

many names changed and cleaned up in implementation. import-only will trigger an import of the tag and then self removal. This is useful for NOT replacing the tag in context but ensuring the definition loads based on passing into the viewport importing-text - what it says as it is visible to the user while importing. This also is the "Click to view" on low power environments import-method - if it should import on view or device capabilities (or automatic, default). View will FORCE a load even on low performance environments while things without this set (like a meme in content) would only load if it's been clicked on for low performance unless the import-method="view" is specifically set.
