Removed four patches.
Improved DESCRiptions.
Improved COMMENT. catdoc is now:
COMMENT=Converts MS Word, Excel and Powerpoint files to plain text
catdoc-tk's COMMENT is made to stay the same.
The catdoc-tk package now installs manpage also.
And don't waste time building catdoc and binaries in catdoc-tk.
(Should catdoc-tk package be renamed to "wordview?")
The changelog is at
http://www.45.free.net/~vitus/software/catdoc/changelog.html
A lot of fixes plus now adds catppt utility to process powerpoint files.
Also has many new character encodings and doesn't install xlsview.
Bump PKGREVISION to 1 because of this. While here, split the Makefile in
two parts to help in the creation of the new catdoc-tk package.
Addresses PR pkg/18730.
