Auto-change Version Text

[charlestian23]

Instead of having the "Version 3.0.0" text have to be manually updated in future versions with a new image, change this to be added by the program like the "Loading..." text. This information can be grabbed from wherever the version number is stored in the program. Additionally, this information should also be changed in the preferences menu and any other place the version of Legup is displayed.

To do:

• [ ] Change version text on splash screen
• [ ] Change version text in preferences menu

Note: this issue should be updated with any other locations that the version text should be changed in the future
