More improvements and more bugs!

The program has had many new improvements fully implemented the past few days.

- zooming in and out is finally -fully- working for splitting and joining in all situations. You can zoom in, zoom out, translate and the splits and joins are still correctly aligned on the bitmap from the ink canvas.

- zooming in and out functions for deleting blobs, you can delete blobs while zoomed in or zoomed out. This is not functioning for any other gestures (erode dilate etc.).

- Icons are now implemented and some of the tool tips have been added. Zoom in and out now have buttons. Additional buttons will be erode, dilate, delete, measure.

- Window now resizes along with he aspect ratio so there is no white space on the sides of the image.

- Tablet works for all usable tools.

- Tablet buttons (set up in windows tablet control) - can do zoom in and out, and switch between the three modes (gesture, split, move). The tablet buttons by default are "not an actual key on the keyboard (2 of these), Left Control, System, Left Shift" so I changed them in the tablet properties menu.

I think that's everything.

Next:

More icons for tools, remove unused icons/buttons if required, erode, dilate and measure to function with zooming features.
