Improve waiting times (for regenerating project files) when adding multiple files in a row

[DenoDS]

Easy way:
Add checkbox whether to regenerate project files to all dialog windows that can modify files in the project.
Little bit unsafe as you can end up with outdated project files.

Better? way:
Support chained adding in "FUnreal: Add Source" with a checkbox at the bottom saying something like "Add another", which would bring up new dialog. Regenerating project files would be triggered only once at the end of the chain.

Hi @DenoDS, thanks for the suggestion.

I was thinking about it but I rather opted out to keep a "transational" approach (to increase safety and consinstency of the project).

Anyhow is an idea I didn't abandoned and could be feaseble. Futhermore this feature should then handle also updating the files tree in Solution Explorer -as a visual feedback - while adding sources (by now this update is obtained as a side effect of the project reload after UBT file regeneration)

Another reasoning I come up with is the following:

• with the "easy way" could be even possible make different kind of operation (add, delete, rename ) and then in the end regenerate (eventually paired with some handy shortcut for the user to disable regeneration and to force regeneration)
• with the "better way" would be more "automatic" but related to a specific operation (like multiple add)
