Added resizing for shapes or images

Now the images and shapes can be resized by holding the tab key and clicking the item. The resizer box appears. Just drag the handles. It will keep the ratio of width and height for images. Shapes that are not required to have the same sides will not hold the original ratio of width to height.

I also fixed a few errors. Search panel position and visibility. And fixed the label for the first time users. That caused a small issue in the listbox showing wrong data.
