Add info on TiddlyHost saving & revised TiddlySpot (#5622)

I updated the English text only. Will need some help with the
translations.

Summary:
- Mention that TiddlySpot is deprecated and doesn't allow site
  creation any more. Suggest using TiddlyHost instead.
- Remove obsolete intructions about creating TiddlySpot sites.
- Misc editing/rewording/tweaking of existing TiddlySpot info
  for tidiness and clarity.
- Add new information about saving on TiddlyHost.
- Add logos because why not..

Note: I usually prefer the non-camel case versions of Tiddlyspot and
Tiddlyhost, but decided to go with the CamelCase WikiWords here to
fit in with the existing conventions.

+[[TiddlyHost.com|https://tiddlyhost.com/]] is a hosting service for TiddlyWiki created by Simon Baird. Once you sign up and confirm your email you can create "sites", (i.e. ~TiddlyWikis), with support for online saving. Sites can be private or public, and you can optionally list them on the taggable and searchable [[TiddlyHost Hub|https://tiddlyhost.com/hub]] where they'll be discoverable by others.
+
+Unlike [[TiddlySpot|Saving on TiddlySpot]], [[TiddlyHost|https://tiddlyhost.com]] is secure, open source, and has proper support for TiddlyWiki5. It also allows uploading existing ~TiddlyWiki files, supports TiddlyWikiClassic, and lets you claim ownership of your ~TiddlySpot sites. For more information see the [[FAQ|https://github.com/simonbaird/tiddlyhost/wiki/FAQ]] and the [[About|https://tiddlyhost.com/about]] page.

-! Setting up a TiddlyWiki on ~TiddlySpot
-To set up a [[TiddlyWiki Classic|TiddlyWikiClassic]], you merely create a new wiki at http://tiddlyspot.com
+[[TiddlySpot.com|http://tiddlyspot.com]] is a hosting service for TiddlyWiki created in 2006 by Simon Baird and Daniel Baird.
 
-!!TiddlyWiki5 on ~TiddlySpot
-~TiddlyWiki5 also functions well on ~TiddlySpot but this version is not offered directly in the ~TiddlySpot set-up.
+In early 2021 it was superseded by [[TiddlyHost|Saving on TiddlyHost]], a new, secure, modern reimagining of ~TiddlySpot. Creating new sites on ~TiddlySpot is no longer supported, (though sites created in 2020 or earlier are still functional).
 
-The simplest way to create a new ~TiddlySpot with ~TiddlyWiki5 is probably through the community created site http://tiddlywiki5.tiddlyspot.com
+!! Security warning for ~TiddlySpot
 
-Alternatively, you can upload an existing ~TiddlyWiki5 document from your local disc to ~TiddlySpot by following these steps:
-
-# Sign up for a new wiki at http://tiddlyspot.com/, and remember the wiki name and password
-# Open your locally stored TiddlyWiki document in your browser
-# Fill in the ~TiddlySpot wikiname and password in ''Saving'' tab of the ''control panel'' <<.icon $:/core/images/options-button>>
-# Click the <<.icon $:/core/images/save-button>> ''save changes'' button. You should get a confirmation notification at the top right saying ''Saved wiki''. Saving can take several seconds if you're on a slow connection or working with a large wiki.
-# Navigate to your ~TiddlySpot URL at http://{wikiname}.tiddlyspot.com/

 ''Is Tiddlyspot secure?''
 
-No. Tiddlyspot does not use SSL/https. Your password is sent in clear text when uploading and when authenticating to access a private site. This means that your Tiddlyspot is vulnerable to packet sniffing and your password could be discovered by a malicious third party. Also your data is transmitted unencrypted when you view your site, even if it is a private site. For this reason please don't put sensitive information such as banking details in your Tiddlyspot and don't use a password that you use for other high security sites.
+No. Tiddlyspot does not use SSL/https, so all ~Tiddlyspot web traffic is vulnerable to packet sniffing. This means your password and site data could be intercepted by a malicious third party. For this reason, please don't keep sensitive information in your ~TiddlySpot site, and don't use a password that you use for other web sites.

 The upgrade operation falls foul of a security restriction in Firefox. Until this can be resolved, we suggest using Chrome.
 
-*# Use Chrome to open the local TiddlyWiki document you want to upload to ~TiddlySpot and follow the steps 1 through 5 described above
