Version 0.0.5 released.

This release consists mainly of a fix for a major bug which prevented the import/analysis of images with differing contrast and brightness values.

The details are as follows:

Fixed several errors when creating new targets from images.
The new algorithm for analyzing images is more robust.
If no good results can be achieved an information message will be displayed instead of dumping exceptions to console.
Added an information message when statistics from menu is clicked but no gun is selected.
