162b091f25 Add kernel argument to Dilate and Erode methods 
A second optional argument can be passed to `mat.erode` and
`mat.dilate`. This argument define the kernel used for this
morphological operation. A kernel can be generated by the
GetStructuringElement function.

e3090f4176 Add GetStructuringElement function 
GetStructuringElement returns a kernel that can be used to perform
morphological operation. This function can be available in `cv.imgproc`
and takes two arguments, the erosion type (MORPH_RECT, MORPH_CROSS,
MORPH_ELLIPSE, ...) and the size of the generated kernel. The `ksize`
argument must be an array of two numbers.
The output kernel is often use for Dilation and Erosion operations.

ec09e0bdde Swapped out all "handle" for "local" 
Now building and passing tests locally in node v0.10.40 v0.12.7 and
v4.1.1. Other modules would not build at node lower than v0.10, so I
stopped there.

a0faef9e65 Here goes nothing... 
So apparently Nan v2 has removed Handle and uses Local instead. Not
sure wtf that’s all about. I have no idea if this works, but it builds
in both node v4.1.1 and v0.12.7 and passes the included tests in both.

cbaff9a133 Make FaceRecognizer require OpenCV <= v2.4.8. 
For some reason OpenCV shipped a broken branch build on Ubuntu 2.4.2 64
bit.

Thanks to @gluxon for noticing this:
https://github.com/peterbraden/node-opencv/issues/56#issuecomment-20263153

Rather than try and be clever, I'm just gonna up the version
requirements.

This fixes #56 #41 #105 #240 and #275
