Multi-block select about nifskope HOT 2 OPEN

A few points of order:

1. I may reappropriate this ticket to include more feature enhancements related to the handling of the NIF data.
2. About milestones: It's not like anyone is setting that in stone, but at this point I don't think we even know what version number we want to assign to the post-Qt5, major cleanup, etc. release. If we decide to make that release 2.0 for example, then this will get pushed to 2.1+. The reason being I am reluctant to make changes to core functionality, as in, changes that could actually mess with the underlying NIF data.

When you talk about selecting multiple blocks, I assume it's regarding Copy/Paste operations? That entire area needs to be looked over carefully as there are already more pressing issues, like actually getting consistent behavior, i.e. blocks actually pasting where you expect them.

Also, insertion of children blocks, via copy/paste or even new blocks is odd. If I right click an NiTriShape, I should expect Insert > NiTriShapeData to add a child if there is none. Or, under the Node menu, in the same vein as "Attach ..." there should be one which lists valid blocks that aren't Properties or ExtraData.

I also would prefer to implement drag/drop for blocks where appropriate, with Copy/Paste still being an option. But that's definitely far future as I'm not sure how well the widgets even support such operations.

I'll eventually get around to making a more fleshed out list of these ideas.

The use-case is being able to select multiple blocks. The context being able to use the selected blocks to mass delete the selected blocks in one go. I have a user request to export the content of which NiBinaryExtraData blocks, essentially .wav files. The provided nif contains 1200~ NiBinaryExtraData blocks and wanted to create a test version with just one.

Currently you can only delete one block at a time via Ctrl + Del which is general quite underperformant as is. Also deletion does not select any block which require additional use input.
