[Options Menu / Issue] - Changing intro music during the intro

[AmusedNetwork]

Fun bug time!

I discovered that changing the intro music from the options screen whilst the intro music is playing changes when the cards show.

For example, (A) using the default long intro, then changing to the shorter "3.. 2.. 1.. Go" intro causes the cards to show while the music is still playing. (B) Conversely, when originally using a short intro, but switching to a longer one, no music plays, but the cards do not show until the newly selected song would have finished.

Steps to Reproduce:

A.

1. Select the "Normal" intro song from the options menu
2. Start the game (note the music starts playing)
3. Change the intro song in the options menu to "Countdown" or "None" while the music plays
4. Notice the cards show after the length of the Countdown / No countdown while the music still plays.
   B
5. Select the "Countdown" intro song from the options menu
6. Start the game (note the countdown plays)
7. Change the intro song in the options menu to "Normal"
8. Notice the do not show, but no music is playing. The cards unflip after the length of the "Normal" music.

Potential Fix:

Do not allow users to change the intro music while the game is running, or have a separate variable to hold options menu variables rather than directly setting them.

Thanks.
