[For 1.8] Link Tools 1.4.1

[Laird]

Hi, and thanks for that feedback, Omar. It's very helpful. You're right about link preview caching: it only supports a single theme (which seems to be the Default theme though, not Master as you suggested, but perhaps we are experiencing things differently for some reason). This is something that I didn't think about at all when developing the plugin, which is an unfortunate oversight.

Note that some Link Previewers don't cache at all, and are not affected by this problem (currently: the "YouTube video" and "Twitter status" previewers).

Perhaps, rather than adding a new development setting, you would find your needs sufficiently met (for now) by either:

1. Working with these non-caching previewers where possible.
   
2. Otherwise using the "Regenerate preview" link in the bottom-right corner of a post with a cached preview while developing (whilst editing the Default theme's templates).
   

To address the deficiency you've picked up, which would permanently avoid the need for the setting you've requested, perhaps the best approach is for each caching Link Previewer to cache in serialised form the information it needs to regenerate the preview rather than the preview itself (e.g., page title, summary, and image url), and then to supply that to the template engine to generate the final preview when the thread is rendered.

Huh. And there I was thinking this feature was basically good to go. Good thing it was only a development release after all.
