Add new improved font for icons, update last comment, reassign ticket to...

Hey Will!  
  I added some of the features back in: 
  Reassigning the ticket will move it to a new column.  
  It pulls in the last comment for the ticket when you view it as well as after you update it. 
  I created a new icon font that is mapped to a letter instead of unused characters to make it easier to use.
Enjoy!
