genlist's height-for-width mode is in. 

I'll commit this to bring some attention to the topic, it is harmless
for people that do not use it, but for users it may be slow on list
resize.

/**
* Set height-for-width mode
*
* With height-for-width mode the item width will be fixed (restricted
* to a minimum of) to the list width when calculating its size in
* order to allow the height to be calculated based on it. This allow,
* for instance, text block to wrap lines if the Edje part is
* configured with "text.min: 0 1".
*
* @note This mode will make list resize slower as it will have to
* recalculate every item height again whenever the list width
* changes!
*
* @note When height-for-width mode is enabled, it also enables
* compress mode (see elm_genlist_compress_mode_set()) and
* disables homogeneous (see elm_genlist_homogeneous_set()).
