For HQ Player developers / Call via AppleScript

Just a simple release that adds a way to obtain the latest sample rate via AppleScript.
Effectively it covers #108 use case.

Example:

tell application "LosslessSwitcher"
	set rate to get latest sample rate
	do shell script "echo " & rate
end tell

Returns:
"44100" on a 44.1kHz track.

Note: on first call/launch, -1 will be returned.
