Makes copy history a bit more informative by showing the code point
range of the selection copied, or the individual character if the
selection contains only one glyph.
Resize the clipboard history size dynamically by listening for config
changes. This is currently not ideal since we don't have the callbacks
for `Config::Listener::config_i32_did_change`, so for now we are just
taking the string and attempting to convert it to an int.
The number of items in history was hardcoded to 20 earlier, now
we try to load this value from a config file. The default if none
is available is still 20.
Most of the models were just calling did_update anyway, which is
pointless since it can be unified to the base Model class. Instead, code
calling update() will now call invalidate(), which functions identically
and is more obvious in what it does.
Additionally, a default implementation is provided, which removes the
need to add empty implementations of update() for each model subclass.
