Proposal for a generic showIntAtBase

[Tikhon Jelvis]

Decomposing numbers into arbitrary bases *already* exists as showIntAtBase.
Vikas's proposal is about generalizing this existing function to output
more than just strings and characters. Whether the existing naming scheme
makes sense is a separate issue. (The whole Numeric module is weird, from
the non-hierarchical name through function like showFFloatAlt.)
