1ac0bd8fe9 Don't clean elements when set back to defaults 
The elements are not shown, thereby a cleanup isn't necessary. When the
elements are shown again, new values are set and overwrite the old one.

ff725e9235 Fix issue that prevents units from being copied 
Units have been placed with the ::after selector. Content showing with
this pseudo-element can't be selected and copied.

Now the units are automatically added when the value is set.

3dc965e8ff Set a single value to several places 
Prior this change items are set to html elements with id of the same
name. Now OOMDisplay._set_item() searches for elements with same-named
id or with item name listed in class attribute.

This allows to set one value to several places to once.

Additional suffixes for pages and kbytes are added in the singular or
plural automatically.

606d0d6769 Use negative slicing with operator overloading 
Positive numbers in slices works well, but for negative numbers you
have to activate operator overloading. This has a (unknown) speed
penalty.
