Title: ScreenCamera class added 

This resolves issue #218.

This class depends on pyscreenshot ( https://github.com/vijaym123/pyscreenshot ) library.

It has the following functionality :
```python
from SimpleCV import *
sc = ScreenCamera()
res = sc.getResolution()
print res # Prints the resolution of the image captured as a screenshot
img = get Image()
img.show() #screenshot image

sc.setROI((1360/4,768/4,1360/2,768/2)) #sets the region of interest
img = sc.getImage() #returns the region of interest in the form of Image.
```
Documentation and test cases added. Any more changes inform me.
Thank you. :)
