Before this commit, the setting search was done exclusively in some
selected texts. These texts needed to be on some specific selectors
(field, label, span.o_form_label and div.text-muted).
Now, all text on a setting are searchable (including the text in
buttons). This commit also re-structure the setting compilers file to
remove the functions outside the class, this is done to standardize the
compilers (setting, form and view).
