Log message:
Update all R packages to canonical form.

The canonical form [1] of an R package Makefile includes the
following:

- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
  needed), and CATEGORIES.

- HOMEPAGE is not present but defined in math/R/Makefile.extension to
  refer to the CRAN web page describing the package.  Other relevant
  web pages are often linked from there via the URL field.

This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.

Log message:
Remove MASTER_SITES= from individual R package Makefiles.

Each R package should include ../../math/R/Makefile.extension, which also
defines MASTER_SITES.  Consequently, it is redundant for the individual
packages to do the same.  Package-specific definitions also prevent
redefining MASTER_SITES in a single common place.

Log message:
Add SHA512 digests for distfiles for geography category

One mismatched digest found in geography/libmemphis02:
	# package libmemphis02
	recorded SHA1 (memphis-0.2.3.tar.gz) = dbc2f61e49b996dc9ca91df0de9a08eb7adbfa9b
	calculated SHA1 (memphis-0.2.3.tar.gz) = 85993bce12c3616fcf6e7682a70b9605883edec2
No changes were made to the libmemphis02 distinfo file

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.
