Pull Request for Issue1081: Split ion chamber class for SR570 sends signals too quickly

It was discovered that the AMCurrentAmplifierCompositeView sends signals to the SR570 app too quickly.  So I added in a single shot timer delay.

@davidChevrier, due to the ease of the fix, I just implemented it in the AM class.  However, this problem is almost (always?) entirely due to the IOC application not being able to handle requests fast enough, which might warrant making a CLS version.  What are your opinions on this?

This also hasn't been tested, but it can still be reviewed.
