std.Progress: Terminate progress escape codes with ST not BEL

Browse source 
`ST` is the "string terminator" and what is actually prescribed in the
standard for escape codes. Use of `BEL` as a terminator is apparently a
historical oddity that persists for compatibility. Unfortunately, not
all terminals support using `BEL`, including Ubuntu's new default
terminal, Ptyxis. Using `ST` should make it work in more terminals.
