- Move `libarchive' from global USES list to SMB where it's pulled
explicitly; otherwise the program's happy with base system's one:
Found LibArchive: /usr/lib/libarchive.so (found version "3.5.1")
- Switch to GTK+2-based wxWidgets: it's noticeably faster and does
not pull heavy and useless (for this particular program) WebKit
- Augment the port description while here, particularly, remove no
longer relevant "alpha version" warning
