This appears to be incompatible with pyinstaller. I get the following
when trying to run the executable generated with pyside6:
```
Traceback (most recent call last):
File "qt_ui\main.py", line 29, in <module>
File "PyInstaller\loader\pyimod03_importers.py", line 476, in exec_module

ImportError: could not import module 'PySide6.QtPrintSupport'
```
Much of the UI was using the old budget which wasn't removed from Game
like it should have been when Coaltion was introduced. The UI displayed
(and in some cases pulled from) the starting budget rather than the real
budget.
This adds both player and enemy income multiplier options. Note that
previously the AI was only getting 75% of their income. I've changed
that to give them their full income by default since the player can now
influence it.
