* Allow the rendering of fields to be extended
This commit extends the `$:/core/ui/EditTemplate/fields` tiddler to
use a new cascade (Field Editor Cascade) to allow customizing the
rendering of the field editor.
It provides a default element for the cascade that displays the standard
EditTextWidget as a fallback. That way, the implementation is completely
backwards compatible. The `currentTiddler` and `currentField` variables
are available in the transcluded tiddler. This has the additional
benefit, that not only the `EditTextWidget` can be used. The user can
use a dropdown-list or even something completely crazy. As long as it
can be put into a tiddler that updates the field, it will be fine.
* Make `select` Tags in Fields look like the rest
This patch updates the CSS to make `tc-edit-texteditor` usable on
`select`-tags as well.
I'm not sure what `-webkit-appearance: none;` is for, but it hides the
DropDown-arrow in Chrome and makes the select-tag hard to discover. I've
changed the css to only apply it to the input tag. Maybe it can be
removed altogether.
* Add documentation for the Field Editor Cascade
