Title: Added Image.read() and Image.clear()

I moved file reading related code into new method Image.read(). I also made few changes to allow calling Image without parameters. With new method Image.clear() it's now possible to reuse single Image object with multiple files:

```python
img = Image()
img.read(filename='test1.png')
#do some operations
img.clear() # <- this clears existing wand
img.read(filename='test2.png')
```
It should now be possible to add functionality to close #28 without polluting Image constructor (I'm working on this).
