* fbt: added separate script for Windows env setup; moved flash targets from firmware.scons to SConstruct; added Blackmagic support with automatic probe port resolution; added apps.c rebuild on any manifest.fam changes; fixed simultaneous flash & debug ops * fbt: added networked BlackmagicResolver mode; added `get_blackmagic` target for IDE integration * fbt: cleanup * fbt: docs update; fixed blackmagic lookup on certain usb hubs * fbt: removed explicit python serial port import * fbt: cleanup * fbt: raising exception on multiple serial blackmagic probes
