GUI Customization

[karastoyanov]

@nikichhh, @DobromirMD Work togheter on that issue.

Take part in the customizing the application. Implement different stylings to the objects inside the GUI --> buttons, text labels, text boxes, etc. You can create different types of text and background effects, transparency, border's rounding, etc...be creative

⚠ Choose the same style for all objects, we want to have a same visual effects for all objects

⚠ Start working with Login and Register menus, once we have one final styling approved, we will apply it to the rest of the windows

⚠⚠⚠ Work only with the experimental branch!!!
