yelp-build epub: Fixed extra dir prefix on media

I'd added an extra "yelp/" dir to hold yelp's autogenerated files
for epub builds, but due to the way I'd structured the code, the
copied media files were also put in that directory. Except the
references to them in the XHTML didn't use the extra prefix.
Fix 'make pot' when srcdir != builddir

yelp-build: Fix directionality issues for Mallard

yelp-build actually uses the cache as the primary input document
for Mallard docs. A lot of the globals in l10n don't work, because
they don't get their info from each page element.
