New Replace part

[Amilcar Lucas]

We have a new part!!!

It does search and replace of stings project wide. (The begining of code
refractoring!!!!)
It was coded by Jens Dagerbo and I've added it to cvs.
If you want to test it (this one is VERY alpha) you'll have to activate it
in the parts/Makefile.am.
Once Jens Dagerbo finishes the tests we can activate it permanently.

Happy coding
Amilcar
