button events. This mode needs to be explicitly enabled at runtime, and does nothing if not configured. As there are now two different modes available, adjust the manpages accordingly, describing what they do and how they work separatedly. While here, remove a bunch of unused stuff (event syntax) from config file parsing. This was initially added with this new mode in mind, but it has not been used to make it a lot simpler.
