Optimized package viewer

The file tree is now created lazily, which vastly improves performance and memory usage on large VPKs.
For example, the Dota 2 pak01_dir.vpk contains 325k files (which also create 40k folders).

This VPK now opens 8 times faster, and consumes 3 times less memory.
This also makes closing the tab much faster as it no longer needs dispose every single tree node.

File previews

There is now a setting to preview files right from the package viewer,
including an option to autoplay sounds.

Selecting a file in the tree view will automatically load it in the right pane,
and selecting a folder will show the folder contents as it did before.

This may be slow for certain big files like models with many animations.
Preview-on-click feature can be enabled in settings.
