Auto-fill routine scripts and add new scripts

[JerBouma]

Description

Just felt like we could use more scripts. Also the bar at the bottom now rotates between scripts as a little neat feature for people to play with. In time, we should have a script for all menus.

See how it looks below:

The following is done:

• Add in more scripts and shorten some. It makes little sense if you have 30 tasks in one script, who checks all of that as a routine?
• Rename scripts to make them conform with one standard
• Add in comments to all of them
• Autocomplete exe and searches in the routines folder.
• Randomly select one of the scripts in the bar below

Question to @DidierRLopes: do you want the scripts with_inputs in here? With no explanation it is really weird to work with. E.g. the fact you need to use -i and add tickers.

How has this been tested?

Not needed.

Checklist:

• Update our Hugo documentation following these guidelines.
• Update our tests following these guidelines.
• Make sure you are following our CONTRIBUTING guidelines.
• If a feature was added make sure to add it to the corresponding scripts file.

Others

• I have performed a self-review of my own code.
• I have commented my code, particularly in hard-to-understand areas.
• My code passes all the checks pylint, flake8, black, ... To speed up development you should run pre-commit install.

@DidierRLopes Wanna share your opinion and/or approve?

Sorry for delay on this. It's bank holiday in UK and have been packing stuff!

I really like this.

I was thinking that the next step is looking into the file and if there is a $ARGV we can ask the user to provide the parameter and if it doesn't throw an error saying that that routine needs an argument. We can do this in another PR!

Agreed!
