This change adds the following options to org.eclipse.debug.ui:

* Console.limitLongLines (boolean)
* Console.limitLongLinesWrap (boolean)
* Console.limitLongLinesLength (int)

When limitLongLines is set, long console lines will be truncated or
wrapped.
If limitLongLinesWrap is set, lines are wrapped. Otherwise lines are
truncated.
The length at which long lines are truncated/wrapped is
limitLongLinesLength.

The preferences apply to output before its appended to the
console document. In contrast, the existing console word wrapping is
applied after the output is appended to the console document.
