Large round of typo fixes in ports/devel (pkg-descr).

COBF (aka C-Obfuscator) is a program which manipulates C or C++ sourcefiles
in a way that they aren't readable by human beings; but they remain
compilable.

WWW: http://home.arcor.de/bernhard.baier/cobf/

Please note: the 'copyright.txt' disallows patching the sourcecode
without explicit permission from the author. Binary packages are not
permitted without shipping the source.

I contacted the author of COBF (emails available per request) and we are
allowed to patch 'src/cpp/makefile' (see 'files/patch-makefile'). He
also permits us shipping binary-only packages (because users can obtain
the source with 'make fetch' anyway).
