All widgets copy&pasted the same description, including an invalid reference
to "Layout", which should be "Elm_Layout".
SOME of them had been fixed over the years but this commit fixes all of them.
This significantly reduces the number of Doxygen warnings and adds meaningful
links to the docs.
These are some of the EO files that shouldn't be part of the public
EO API:
- elm_access (old)
- actionslider
- bubble
- diskselector
- flipselector (a fancy spinner)
- hoversel (use combobox instead)
- icon (use image instead)
- inwin
- naviframe (unreplaced for now)
- photo (use image)
- prefs
- segment control
- separator
- slideshow
- thumb (use image)
Note: This breaks the use of the elm_widget_xxx.h headers. Those
were internal headers anyway. Exposed because of a lack of
a proper inheritance API.
