An over-long pre-chat value came back as "Must be at most 128 characters"
with no clue which field it was about, so use the existing fieldTooLong
message. The home screen also offered the start button when the inbox says
visitors cannot start conversations, and the visitor only found out when
the send failed, so the button now follows the same rule as the server.
Adds a browser-level livechat suite that embeds the widget on a host page
the way a customer site does, drives the real widget UI, and covers every
livechat config option that has a visible effect. CI needs the widget rate
limit lifted because the suite makes more than 100 widget requests a minute.
