Get rid of the doc & seqtext fields, as they are not actually used (nor are they particularly useful, the event handler's name should be pretty self-explanatory). Also, tweak the key_events documentation to highlight the quirks of the API, especially as far as array nesting is involved... Random drive-by cleanup of the declarations of key_events & ges_events to re-use the existing instance object (now that we know they're sane ;p) for tables with a single member (less GC pressure).
