Window titles should be shortened in the launcher context menu

[Ari]

--- Steps to reproduce ---

1.) Open up an application with a long window title (e.g. head to http://www.reddit.com/r/AskHistorians/comments/15mmq8/odd_request_on_very_specific_information_im/ with Google Chrome)
2.) Display the context menu by right-clicking on the appropriate launcher

--- Bug description ---

Window titles are displayed in their entire length when right clicking on a launcher. With long window titles this makes the context menu extend over the whole length of the monitor (see screenshot 1)

--- Current behaviour ---

Window titles are displayed in their entire length.

--- Expected behaviour ---

Window titles should be shortened (see screenshot 2 for how window managers like openbox handle this).
