Adds possibility to select one of 3 text sizes:

• 14pt (the original/default size).
  
• 16pt
  
• 18pt
  

Not everything is sized larger when choosing one of the bigger sizes. Things like titles etc. that were already larger stay the same size and a few labels here and there stay small but the most common things like the dialogs, buttons, hover-help, etc. will all have larger text.

I've probably missed a good few instances where text doesn't fit or gets cut off or something. Just let me know if you see something like that and I'll fix it.

I hope this together with the recent controller support will make TAXINAUT a lot more playable on things like a Steam deck. Next I will be working on adding some more storyline to get some more advanced weapons etc.
