BL-815: Improve previews of templates

- locate xmatter CSS correctly
- hide images with no src
Don't cut off name when creating source collection (BL-733)

Cut off was caused by BetterLabel which was to high, overlapping
the text box. We don't really need a BetterLabel here, so I
replaced it with a regular Label control.

Also anchored the text box and the HTML label that shows the path
to the right so that the full width of the window gets used.

Don't cut off name when creating source collection (BL-733)

We keep it there by adjusting the "bottom" property of the cog every time the scroll of the parent edit box changes.

Fix xmatter mixin that marked all cover pages as frontcover
Introduce less version of factory-xmatter, with no changes.
Add a new xmatter pack named "traditional"

 This puts the credits page on the back of the title page, rather than the inside of the front cover. This is good in cases where you pay by the page imprint, rather than by pieces of paper. You can select it from Settings:Book Making:Front/Back Matter Pack. Once you have chosen this, you won't see it on any existing books until you do these steps: In the Collection Tab, click on the little triangle, then select "Advanced: Do Updates of All Books".
