Load all families from folder tree

[DuncanLithgow]

Is your feature request related to a problem? Please describe.
When testing families that would normally be in a content management system it's useful to be able to load many families at once. A tools for this would be great.

Describe the solution you'd like
There is a 'Load more types' Family tools. I'd love a 'load more families' tool which accepts a folder as input and then asks if all families should be loaded recursively. Trying to filter backups out would of course be a good idea, other wise a warning is fine.

Describe alternatives you've considered
Loading them one at a time ... boring

Additional context
Suggestions:
Name: Load Multiple Families
Description: Loads multiple Families from a folder structure, while trying to avoid backups
Options: yes/no: load recursively. Radio buttons: load only family or load all types from Type Catalogue

An extension of functionality would be a dialogue like the purge dialogue which allows for selecting individual types to be loaded.

@DuncanLithgow
Liked the idea, made the tool -> LoadFamilies.pushbutton
Since I don´t have a large set of tools, I did not create a whole extension. You can create you own extension , if you don´t already have a custom one, and add this tool.
I could only test it for myself - Let me know how it goes for you.

@eirannejad
Many parts are based on your Load More Types tool. Credit can be found in the docstrings of the classes.

@hikmet-kibar This is great. I'll grab it from your repo and will add to the toolbar
