Minor Maintenance Update

Minor version update is live for BackPacker. 

This is a quality of life improvement patch with no major change to the application in regards to form or function. That is why this is only a update from v1.0.1 to v1.0.2.

Formerly for every image file added, the directory path was reset. This quickly becomes tedious when you need to add multiple image files and have to hunt through directories every time. In the recent patch, after selecting an image file, the next image node added will start from that directory instead, saving time.

Some performance optimizations were made as well to improve it's usability further. Fewer paints to the screen, etc.
