Splash screen, parent keyword, undo, redo and paste

Changelog

After many months I can finally release a new version. I'm really sorry for the delay but I'm currently working full time on my bachelor's thesis so I don't have much free time to work on ImHex right now. Hopefully in a few weeks again though :)

Additions

Light mode, Node data processor, custom encodings and more

Changelog

Additions

• Pattern language additions
  • Added new built-in functions
    • addressof : Gets the address of a variable
    • nextAfter : Gets the address directly after a variable
    • alignTo : Aligns a value to the provided boundaries

    • comment : Adds a comment to the variable in the pattern data view
• Added Light and Classic color mode, changeable in the new settings interface
