A few test changes...

To see how you all like them... more on the way...

1) ``.touchs``... why is it called "touchs" and not "touches"? I changed it to "touches".

2) Some of the double if statements were turned into a single if statement.

3) No need for an Internet Explorer window.event fallback. That for IE8 and below, which pretty much has almost 0 canvas support.

4) Cosmetic changes to make the code more readable, like converting single-statement if statements from 3 lines to 1, and standardizing if statements...

OLD:
````
if(a) {
    x();
    y();
}

if(b)z();
````

NEW:
````
if (a) {
    x();
    y();
}

if (b) z();
````
