Adds a search button to the conversation header and shows the matches in the right sidebar: it searches the whole session history through the host log rather than only the messages already loaded, highlights every keyword in both user messages and replies, and jumps the conversation to a chosen hit. It keeps working when the full-text index is disabled.
