[Xerte] New Version

[Julian Tenney]

There is a new version of Xerte you can download that addresses a few
issues recently reported:

- fixed the video alignment being out by one pixel;
- in page templates, the text size can now be controlled by one global
property on the Learning Object icon, rather than setting the text size
for each page.
- new iconID.constrain(w,h) function to resize an icon to fit in a
rectangle defined by w and h;
- new displayIconID.distortImage(x1,y1,x2,y2,x3,y3,x4,y4) to manipulate
a loaded image (from the Sandy3D library's DistortImage class);
