ClipboardHistory: Listen for configuration changes

Browse source 
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.
