All checksums have been double-checked against existing RMD160 and
SHA512 hashes

games/*: fix alignment of variable values

pkglint -Wall -r --autofix --only aligned

After running the above command, three packages had to be adjusted
manually:

In maelstrom-x11, pkglint didn't see that a commented variable
assignment should have been re-aligned as well.

In netmaze, there was a single line that didn't align well with all the
others, but pkglint decided to adjust the whole paragraph to this single
line. The result would have been ok, but not good.

In tscp, there was a paragraph where some of the lines were indented
one space more than the others. This rule is useful when one variable
name is very long compared to the others, but not in this case.

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.

Log message:
Bump all packages that depend on curses.bui* or terminfo.bui* since they
might incur ncurses dependencies on some platforms, and ncurses just bumped
its shlib.
Some packages were bumped twice now, sorry for that.

Add USE_TOOLS+=nroff to packages which generate catman pages.

Really use consistent prototypes.
