[fikira] Bollinger Bands + Higher Time Frames

Here is my take on BB and MTF, based on the most excellent work of
"PineCoders" (MTF Selection Framework functions)!

The big advantage is that on 1 image you can easily see where
price is compared to 5 or less BB Bands (each of different Time Frames).
This gives a lot of Support and Resistance area's!

Includes:
- 1 Bollinger Bands (can be enabled/disabled - "Bollinger Bands"
- 4 Bollinger Bands (each can be enabled/disabled - "HTF Selection 1-4")

Each BB has its colour (can be changed)

- Labels (Timeframe and price) can be enabled/disabled
- Labels position and size can be changed
...

Notes de version:

Streamlined updated version by "PineCoders", thank you very much "PineCoders"!

Notes de version:

- Added 2 more Time Frames

- Since the bands are often distracting, I also added a button to
enable/disable them at once (so you don't have to disable every single band)

> disable "Show BB bands"

> enable "Show BB bands"

It is also possible just to show the colour fill between bands

> enable "Colour fill between BB bands"

A bit "arty" isn't it? :)

Notes de version:

Updated the labels
