Fix event-title max-width in the dashboard
Created by: dsander
For view port sizes between 1260px and 1200px pixels the event-title was too wide, thus not truncated and got pushed into a second line.
100% - 174px was chosen as the max-width because 141px is the widest .event-item-timestamp can get (with 'less than a minute ago') + 24px for the avatar + 8px avatar margin + 1px to fit into the gap.

After:
For browsers that do not support calc, 70% width is the widest possible percentage value which prevents the title from wrapping into the second line.
