7-Zip plugin: support additional formats

[janrysavy]

I’ve been thinking for years that we should add full 7-Zip support to Salamander. It can handle a ton of formats:

Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
Unpacking only: APFS, AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VHDX, VMDK, XAR and Z.

This could allow us to retire many of our specialized plugins.

@KRtekTM what do you (and Codex) think?

@janrysavy I’ll love having this feature, but first I need to catch up on what’s already piled up on my desk. :)

7-zip SDK updated and additional formats added in 7-zip plugin 1.32, will be released with Samandarin 0.9.
