Ship Odyssey: New UI Updates (new Next Site and End Mission buttons, control panel styles cleaned up and simplified, eg. fewer fonts)
Ship Odyssey: create a Graph view in DG, if not present already.
Ship Odyssey: previous mission data can now be deleted
(a work in progress, no user changes for now, until UI is built)
ShipOdyssey.mxml: add sendDeleteAllCaseDatatoDG();
Merge branch 'seg-srri-umass-tp-data-games/master'
Ship Odyssey: Added a 'delete all data' checkbox to the mission screen. Put in mission instructions.

Fixed a little bug on the mission map. MOUSE_DOWN was being used where MOUSE_UP belonged.
