Generalised Io in the Parser to use an IoManager.
Added SystemIoManager to mimic previous behaviour regarding Io.
Added Console to VIBE.
Console implements IoManager and is used by VIBE for Io.
VIBE can now be used free from the Eclipse console!! :D

Still some minor bugs with Console. It seems to occasionally throw 
errors, but I've been unable to reliably reproduce them. 
Keep an eye out.
