OpenACS

This change included new tags for rendering icons and toggles. The

change makes it possible that an unchanged markup of icons can be

adapt itself according to a theme or a manual configuration. One can

use e.g. for Bootstrap 3 glyphicons, and when changing the theme to

Bootstrap 5, then bootstrap icons are used.

Furthermore, the new markup eases maintenance and helps to achieve a

consistent look-and-feel also, when design decisions are altered.

Both, bootstrap-icons and glyphicons are font-based. This leads as

well to a better user experience, since the number of requests are

substantially lower than with the previous approach based on .gif and

.png files. When the iconset is set to "classic" (package parameter in

acs-subsite), the old image files are used.

- new tag: <adp:icon name="NAME" title="..." style="..." class="...">

 Icon-names available for all iconsets:

   edit

   trash

   radio-checked

 The page acs-admin/package/bootstrap-icons/sample contains more

 detailed information, including the names which are identical

 between bootstrap 3 and 5.

- bumped version number of acs-templating to 5.10.1d6
