Nice. And congratulations for finally finishing it. :-)

I have not tried it yet but the example animations look good.

A few comments:
 
- from what you write in the documentation about the collisions i conclude
you have not solved the 'particles penetrating the surface'-problem.  You
might try function based environments like i'm using for my mechanics
simulations.
 
- i have not checked the code but from what you write in 'Inner workings'
gravity is added to the position ("Each particle is moved by it's current
velocity (current location minus last location) plus gravity (for example
-y)") while it should be added to the velocity in fact.

- i am somewhat astonished about your license conditions.  I understand if
you don't want others to modify your tool and redistribute changed
versions but requiring everyone to contact you before publishing a
picture/animation using your file seems a bit exaggerated.  

Forbidding to use your include file for producing commercial work is to
some extent understandable - you don't want others to make profit with
something you put a lot of work into and none the less give away for free,
but on the other hand such a restriction will almost surely prevent a
great success of your tool since a lot of people will refrain from using
it from the beginning with such a restriction.
