Added _normalizeDates function [1303]

Not in use just yet.
Various Jython ADDE fixes [1303]

* It would be nice if I hadn't committed _normalizeDates with a syntax
error. :(

* Finally came up with a decent way of building ADDE URL format strings
(even with all of the optional clauses).

* listADDEImages now returning nominal time rather than start time.
listADDEImage works with multiple dates [1303]
better python style in _normalizeDates [1303]
excised (most) dead code from listADDEImages.

Removed commented-out "addLayer" method. [1303]

This became "createLayer" instead.
Javadocs. [1499]
Fixed some incorrect javadoc links. [1499]
Fixed startup manager javadoc warnings. [0]

I should probably qualify that by saying the "warnings" refers to the
warnings generated by "ant javadoc".
too eager to deprecate [0]

plus it doesn't make much sense to deprecate a private method. sorry. :(
implemented _Display.getMapLayer() [1303]

Also the implementation is no longer *quite* as dumb.
Fix createLayer error message and use getMapLayer.

D'oh. [1303]
