Add a "close plugin library" button (#2072)

Browse Source 
* provides a "close plugin library" button

* starting from #1718 by @inmysocks
* possibly fixes all of #1718, #1597,  and #2067

* corrected code comment

* add back title

No idea why I overlooked this beforehand.

Next time I will not suggest such changes that have little to do with
the PR, but rather just comment the code.

* ah, sorry, "fixed" wrong spot

now

```
<$action-sendmessage $message="tm-load-plugin-from-library"
url={{!!url}} title={{$(assetInfo)$!!original-title}}/>
```

...should be back at the right spot.

* mhhh... still fixing the mess

load, unload, puh... let's see if I got it now

* added unloadIFrame and minor syntax fixes
