Log message:
Remove mk/find-prefix.mk usage from the cad category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Do it for all packages that

Let me know if you have any this time.

Bump applications PKGREVISIONs for python users that might be using
python3, since the default changed from python33 to python34.

I probably bumped too many. I hope I got them all.

Log message:
The icon-theme-installer tool makes use of a GNU sed extension, and so
behaves incorrectly on many platforms (E.g. NetBSD)

https://bugs.launchpad.net/geda/+bug/1319785

Fixes build on Linux, corrects icon file names on NetBSD and others.

Bump PKGREVISION.

Discussed with dmcmahill@ - but as we're both right-thinking people that
understand that desktop icons are for pussies, strictly speaking this
has been build-tested and brain-tested only.
