Use Timeline filtering to hide/show events

[GoogleCodeExporter]

Right now TimeMapItem.hideEvent and TimeMapItem.showEvent use the expensive
tactic of actually removing events from the Timeline - it would be much
better to use Timeline's built-in filtering functions, described here:
http://code.google.com/p/simile-widgets/wiki/Timeline_highlighting_and_filtering

This would most likely go into TimeMap.initTimeline - something like a
filter that returned item.eventVisible.
