feat: select all for code inputs

This enable the "select all" feature for `input.select-all` element.
input elements are used because these are the only one with the
`select()` method.
To obtain the same rendering as before the readonly attribute and the
class `code` have been added to these elements.

@vincent-peugnet: make sure to use this element for future select-all

Closes #107
