record audio with arbitrary length

[GoogleCodeExporter]

What steps will reproduce the problem?
Record an audio message by pressing on the headset (or touchscreen) button

What is the expected output? What do you see instead?
This gives a list of possible audio duration length: 2s, 4s...
These are the only options available with both touchscreen and headset buttons: 
I read somewhere else that it may be possible to record audio message by 
keeping the headset button pressed as long as we need it, but this does not 
work.

I think a useful enhancement would be to give the option to record audio with 
arbitrary length by pressing the button twice: on start, and on stop.

What version of the product are you using (See "About" screen)?
v0.6.6

Make/model of your device, and Android version?
samsung galaxy Y, android 2.3.3

Please provide any additional information below.
I can take care of implementing this feature if you agree.

Hi,

Yeah I think the "keep button" pressed thing never worked very well. That's 
fine with me if you want to replace it with start/stop.
