Start decomissioning some latex ports

Remove indefinite articles and trailing periods from COMMENT, plus
minor COMMENT typos and surrounding whitespace fixes. A few Makefiles
where not included as they contain Latin-1 characters that break
the Phabricator workflow. Categories P-S.

Fix properties on pkg-plist

Add NO_STAGE all over the place in preparation for the staging support (cat:
print)

Rectify USE_TEX to support both of teTeX and TeXLive.

TEX_DEFAULT:
	A knob to choose teTeX or TeXLive.  One can specify in /etc/make.conf.

USE_TEX:
	A knob for port developers.  Valid keywords are listed in
	bsd.tex.mk.

Remove *_DEPENDS from ports which depend on teTeX and add USE_TEX=tetex
instead to make migration to TeXLive easier.

Add latex-feynmf 1.08.19961202,

feynmf is a combined LaTeX/Metafont package for easy drawing of
professional quality Feynman diagrams. feynmf lays out most
diagrams satisfactorily from the structure of the graph without
any need for manual intervention. Nevertheless all the power
of Metafont is available for more obscure cases.
