Ticket #3058: Add 'hex' to the pretty package (and other thoughts)

Attached is a patch for Text.PrettyPrint.HughesPJ that adds a 'hex'
function to print hexidecimal numbers.

The only point that I exepect to be contended is it varies slightly from
the surrounding functions in that it allows one to control the number of
characters printed:

> hex 5 31
> hex 2 8
> hex 3 7495

While we can argue about the consistancy issues, I almost always want to
control the number of digits when dealing with hex.  Hence I feel this
is a reasonable special case.

Secondary Issues:
1) Is there a repo for pretty?  I didn't see one on code.haskell.org
2) If I submit a ticket+patch to move Text.PrettyPrint.HughesPJClass
(from prettyclass, Augustsson) into Text.PrettyPrint (of the 'pretty'
package) would anyone object?  It feels mis-placed / I feel things need
