Yelp POTFILES updated

[Don Scorgie <Don Scorgie org>]

Hi,

I've moved various files from POTFILES.in to POTFILES.skip as they are
now obsolete.  I don't know if this affects translators but better safe
than sorry ;)

The files now in POTFILES.skip are:
src/yelp-db-pager.c
src/yelp-db-print-pager.c
src/yelp-info-pager.c
src/yelp-man-pager.c
src/yelp-pager.c
src/yelp-search-pager.c
src/yelp-toc-pager.c
src/yelp-xslt-pager.c

Thanks
Don
