Safer destructive actions

Fixes #298
Fixes PolyMC/PolyMC#948. Well, it obviously won't actually close the issue. I went further though - some may say it's too hard to do dumb things now.

• Confirmation when deleting multiple resources (mods, resource packs, etc.), or if they are folders.
• Confirmation when deleting servers. Since servers are nothing much more than IP addresses maybe this should only show if it's an IP address rather than a domain.
• Confirmation when uploading logs and screenshots.
• Confirmation for removing component customisations either by pressing remove or revert. Some may say this isn't very useful since there's no multi-select.
• Move a lot of things to trash instead of completely deleting them.
• Improved consistency.

Unfortunately it still says "may be permanent" which in my opinion is not really great. Perhaps it could be adapted to whether Flatpak is being used, and perhaps the whole dialog logic could be moved into a utility since it's now used a lot.

thanks for the contribution :)

i agree a utility for the confirmation dialogs would be useful here, perhaps somewhere in CustomMessageBox or GuiUtil, possibly with different functions for single item and multiple item confirmations. doesn't necessarily need to be in this PR though
