app: allow to toggle tags and then write text with that style

instead of using the toggles only to change the style of selected text.

Introduces a list of "insert tags" in GimpTextBuffer that is applied
on newly inserted text if it exists. Clear the list on each content
or cursor/selection change, so we always display wthe style at the
cursor unless the buttons were clicked explicitely.
