Taking writeImageAtIndex off of EDT [1500]

Also I got Inquiry 1500! Woo?
VERY initial version of listADDEImages [1303]
more listADDEImage work [1303]

Now returns a list of dicts suitable for passing into getADDEImage…some
work still needed though (e. g. "should lines/element or lat/lon be
preferred?").
Merge pull request #60 from tommyjasmin/master

Avoid directory scanning at startup (thanks Ghansham) [0]
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.
