displayExceptionWithInfo is not exported from base

[alt-romes]

Since #285:

By default, uncaughtExceptionHandler uses displayExceptionWithInfo to print uncaught exceptions. This default can be overriden with setUncaughtExceptionHandler, for instance, to present custom error messages on exceptions to the user.

Unfortunately, as an oversight in the proposal, displayExceptionWithInfo is not exported from base.

I propose we export displayExceptionWithInfo from base. It seems natural and useful say, if one wants to override the default but provide displayExceptionWithInfo as a fallback without having to re-implement it.
