Version 0.9.0-Beta part 1

Multiples changes:
-Fixes a crashunder certain conditions while opening or exporting files and folders.
-Add VP/VPC editing / creation
-Add file previewer

Previewer uses Magick.NET to handle image files and LibVLCSharp for audio and videos.
All formats except for .ani are supported for preview

What left for part 2:
Text file preview on a separated window for tables, scripts, etc
Settings configuration window, mostly for the previewer.
Support for configurable 3rd party external viewers
