Webclient: revise renderer helper + CSS classes

[jri]

The Webclient CSS classes "type-icon" and "menu-icon" should be dropped. They do not properly separate semantic and style.

[Jörg Richter]

Revise renderer helper + CSS classes (#580).

BREAKING CHANGES

Webclienr Renderer Helper:

• dm4c.render.type_icon():
  • the image element rendered is of class "icon" (not "type-icon")
• dm4c.render.icon(src, title):
  • the image element rendered is of class "icon" (not "type-icon")
  • if "title" is not specified no tooltip will appear (formerly the "src" was shown)

Webclient CSS:

• class "type-icon" removed.

It was defined as:

.type-icon {
    border-style: none;
    vertical-align: middle;
}

• class "menu-icon" removed

It was defined as:

.menu-icon {
    border-style: none;
    vertical-align: middle;
    padding-right: 12px;
    width: 24px;
}

=> If your plugin relies on these classes it must be adapted.
Basically you might be interested in the reduced icon size (width: 24px).

See #580.
