When the user selects text, the editor compares its closest block type
with a pre-made list of text types (eg. p, h1...).
In case of a match, the 'active' class is applied on the relative
toolbar component.
This commit will extend the comparison list adding text styles that were
initially missing (= the code, h4, h5 and h6 tags were never marked as
active).
