Krecipes 2.0 alpha 6

[José Manuel Santamaría Lema]

Hi,

after releasing 2.0 alpha 5 I realized that Krecipes fails to build with gcc 
4.5, also I discovered that linking the program against PostgreSQL and MySQL 
development libraries was not neccesary. So, I'm releasing again to fix this 
issues. This release also includes a few other bug fixes, see the ChangeLog file 
for details.

Cheers.
