IIIF protocol and IIPImage iiif-compliant fork

[regisrob]

Since IIPImage delivers images through URLs with a "iiif" parameter (http://example.org/iipsrv-iiif.fcgi?iiif=image.tif/full/full/0/native.jpg), iiif.js translator does not work out of the box because urls are constructed with "server + "/" + image" (required parameters are passed over…). It should be "server + "?iiif=" + image", unless you have some rewrite rules (which I didn't manage to set up properly).

I tested IIPMooviewer in front of IIPImage (with iiif support from klokantech's fork) and faced #38, #39 and the present issue. I did some workarounds that did the trick and finally make my demo work.
But there is a final issue with one tile at zoom level 1 and 2 (the size of the bottom-right tile is wrong and does not fit). I guess it is a math problem somewhere (I suppose it is on the server's side and not the viewer but not sure...).
