[Enhancement]: Extract/Compress archive files

[pkerschbaum]

Motivation

The file explorer should be able to extract archives (.tar.gz, .zip, .rar files) and also to create such archives based on the currently selected files.

Ideas

Extraction

• New button in ActionBar: "Extract Archive"
• The button would only be enabled if exactly one archive file (.zip, .tar.gz, .rar) is selected.
• After click on "Extract Archive", a popover containing a form appears which asks for the name of the resulting folder (similar to the button "New Folder").
• After confirming the form, an "extraction" process is added to the processes area (lower left corner) which extracts the selected archive file into the folder entered by the user, in the currently opened folder.

Compression

• New button in ActionBar: "Compress to ZIP file"
• After click on "Compress to ZIP file", a popover containing a form appears which asks for the name of the ZIP file (similar to the button "New Folder").
• After confirming the form, a "compression" process is added to the processes area (lower left corner) which compresses all selected files&folders into a ZIP file with the given name, in the currently opened folder.

See this annotated screenshot (using the "New Folder" popover just for demonstration purposes):
