Incorrect Device Detection

[nikitaeverywhere]

Affects all WebTerminal versions.

Being executed in the standard Caché Terminal, w $IO gives string like |TRM|:|10432.

When doing the same in WebTerminal, it returns null device like //./nul:9708.

This is not critical at all, until the program being executed checks which device does it use. Some system routines perform this checks (like ^%GD, #76 related), and result with different behaviors regarding to the output. This is not good as WebTerminal must behave as close as possible to the standard Caché TERM.

This would become a great step forward if this issue get resolved.
