Auto-assign custom speech audio

When Auto-name speech audio files? is unchecked, the user is required to assign audio clips manually.  This is better for performance, but can be a slog for games with lots of speech audio.

The script searches your Resources folder and automatically assigns files used when the checkbox above is checked.  The required filenames are given in the Speech Manager when this is checked.

For example, the Demo game's Player lines are audio files of the format:

/Resources/Speech/Brain39

This will locate the auto-expected filename and assign it into the manual Audio clip field.

To use, make sure your speech lines are correctly named for auto-assigning, and place them in the appropriate Resources folder.  Then place this script on a GameObject and run the scene.
