Improved Tutorial, Improved GUI's, Graphics, more.

Improved Tutorial, Improved GUI's, Graphics, added a line renderer to
form as the endoscope's trail so that the user knows where the
endoscope is and how further in he/she is. Added endoscope/lesions
collisions as well as particles/lesions collisions. Lots of bug fixes.
