Improve part list

[Bouni]

I wanted for a long time to replace the part list with something that lets me add, change or delete entries without having to re-populate the entire list every time a change is made.

I think the way to go is using a DataViewCtrl in combination with a PyDataViewModel.

That also allows to sort the columns using anatural sort algorithm without having the database to do the sorting.

I'm currently working on a POC but that takes some time as it is a massive change

For those who are interested, I created a small test wx frame that uses DataViewCtrl and a data model PyDataViewModel.

DataViewCtrl: https://gist.github.com/Bouni/28651a1a6cc2dd4d2749612097801f97
datamodel: https://gist.github.com/Bouni/659b6f8a10132b6536a010f83f785c02

Natural Sort works without database, adding elements, modifiying elements and deleting elements works as well.

Still to do: Select alike, center icons

@Bouni what would the purpose be to add/update/remove entries or is that just showing the low level functionality of not having to rebuild the list each time?

[Bouni]

Yes, Just test if everything we need works. With buttons for this test but later automatically

Ok, so I added the datamodel and the DataViewCtrl into the Plugin as a basic test and it seems to work fine!

All Sorting is done without the database, I only poulate the List initialy from the database

I work on a PR that integrate this into the plugin, the changes will quite extensive as a lot of logic is no longer necessary
