Merge pull request #175 from rixter13/master

Added a popup message for the topic and use correct timestamps - fixes #144

Added a popup box when the mouse is held over the topic, and added html
escaping for the single quote ' so if a channel uses contractions it
will popup the entire message instead of stopping at the first single
quote '

Strange hack to fix the date/time bug in the topic. Seems like the
number is being truncated for some reason, and its coming from the
server in epoch time (divided by 1000 that is)...
