Add variable periods to Awesome Oscillator

[joonis]

The periods of Awesome Oscillator (AO) are hardcoded to 5 and 34.
They should be variable by passing them as options.

Please provide your reasoning.

Do other charting libraries/programs allow AO with other periods?

[joonis]

Well, generally you are right. Most libs use hardcoded periods for this indicator.
But there also exist other libs:

If you are working with intervals other than days (eg. hours or even minutes), it is useful and sometimes required that you can adjust these periods.
