How-to make a busybox-w32 installation more or less portable

_ busybox portable how-to.md

Make a directory somewhere to be used as base directory for the busybox-w32 stuff itself (eg. C:\Tools\busybox). The busybox-start.cmd script would be useful to start an interactive command line from the desktop.
