Fixes and Formating

I have been very busy of late with a new job, although I am still not finished, i wanted to upload the progress I had so far on finishing this expansion.  I am going to format to individual cards and still have to fix the Investigators, back stories and Location encounters.  I have changed Cthugha epic monster, fixed wording and errors I caught on cards so far.  Nygotha Research encounter 23 was missing, so I made a new card.  I also started to add an Expansion Icon to cards.
