Works on all three UIs offers a generic function to ask a question that platform independent.
If the user fails to offer a response, the installer will terminate.

In the GUI this still works, however it may not be desirable to prompt the user for each question.
So long as we don't attempt to access the variable before the user has had a chance to put in their preferences it will not prompt them
Changed the GUI to gray out the other widgets if the product is not selected.
start_ensure_config is called AFTER product is set, if it's called before it attempts to figure out which platform it's on, prompting the user with an additional dialog (not ideal, but acceptable)

and migrate APPDIR_BINDIR and WINESERVER_EXE

fixed circular import issues, and initial startup errors

trying to avoid monster object being passed around a ton

removed RECOMMENDED_WINE64_APPIMAGE_BRANCH as it wasn't used
RECOMMENDED_WINE64_APPIMAGE_FILENAME as it was only used as an intermediate to get the version, not use storing in it's own right.

combined SELECTED_APPIMAGE_FILENAME (stored) amd APPIMAGE_FILE_PATH (was only in-memory before)

variable did nothing, replaced with a string

automatically invalidate network cache after it expires

keep in mind this doesn't run enforce_icu_date_files on update

and starting to migrate from msg to the abstract class

removed curses.KEY_RESIZE, there wasn't a RESIZE at refactor time

start using app.status rather than msg.status
