Fixed imagemin

Imagemin wasn’t attached to watch and the image folder(s) weren’t being
watched
Mouse major update

Added mouseClick, mousedown, mouseup and context.

moucseclick now accepts a local callback so do all the other functions.

context disables the right click context menu based on
this.allowContext being true or false

mousedown has an interval which can be set and the interval is cleared
on mouse up

mousedown also accepts and extra parameter to define which button
(left,middle,right or wacom?)
Sprite move

changed the default position to off canvas.

added very basic velocity chichi is applied on canvas draw.

removed offset from setPosition bad practice.

added move function which modifies the velocity object intern allows
the applyVelocity function to activate and do something on canvas
update.

apply also checks if the sprite is on the canvas and if it isn’t just
returns to free up some resources.

Although the sprite isn’t being reused or removed, so that’ll need to
happen.
