On creation/edition module, allow to increase textual box size

[mgerbaux]

For textual field, boxes are sometimes too small to work properly (for example for article).

In this screenshot, its obvious that this box could be higher for this screen

In V5; such boxes could be increased at demand

Moreover, the box should be resizable only for the height and not for the width.
To do that :

• Remove !important attributs on all rules for height on textarea (there are several rules...).
• Add the rule on textarea :
  resize: vertical;

exactly what I wanted to do, thanks for pointing it out.
Maybe a good idea would be to implement an automatic height, getting bigger with text?
It even is the case here, in the comment textarea of github.

Just a comment (if Textarea auto height is doing the job):
Actualy, we can resize textual fields but only the widht :
