Log Message:
Update to 3.6.1.

Removed four patches -- three are integrated and antiword is removed.

No longer conflict with antiword.

Add patch (from OpenBSD) in attempt to fix egon.

Improve DESCR.

Add http download to MASTER_SITES.

Don't depend on gv or gnuplot. gnuplot is optional. And I don't
know why it depended on gv. This package provides its own postscript
viewer.

ChangeLog has:

061110	Buildability fixes for Egon.
	Unbundled Antiword.
	Corrected formatting errors in dictionary.it.
	Bundled o3read.

030916	Siag, PW: Ctrl-T adds sheet, Ctrl-W removes sheet.

030820	Got newest source from CVS. xsiag/window.c had to be
	reformatted using indent.

	mwApplicationShellWidgetClass. Instant drag and drop
	support, just like that. This means that Mowitz >= 0.3.0
	is now required.
	Siag, PW, Egon: remove drop.[ch] and use drop functionality
	in Mowitz instead. Added cb_drag and cb_drop callbacks.
