curses and some minor stuff

There is progress on that ncurses thing,, you can even compile the editor with#include <curses.h> and it seems to work too, but without colours.

Also i am working now on language dependent files, so you can configure the editor to use the language you want to display menues, textes, error messages and such (of course someone must create such a language file before...)

Macros can use those files too, because they can access the *.cfg file too.

The language used is taken from the environment variable $LANG. This value can be overwritten in pipedit.cfg at the entry language=
If none of both exists, the default "en" (=english) is used.

Plus some minor stuff added, behaviour of the cursor, current line in the text number is marked by a red line number, and such.
