Improved debugging in vt100 consoles.
* Added 'debug' option to vt100cons and vt100busdevcons --console-title configs so you can get debug out of console creation without recompiling vt100.dll
* Rejigged FSHELL_AUTOSTART macro so it supports textshell mode via an eshell autoexec.bat
* Fixed some issues with FSHELL_NO_BLUETOOTH_SUPPORT
