Nyagua 3.1 released

Hi everyone.
the new version of Nyagua has been released.
Some features has been implemented to get a more usable interface, reports have been improved (particularly expenses report) and (for the first time) some things has been removed.
The fertilizer calculator contains no more calculations on commercial products. Some people has write to me facing the point that we can only suppose what are the components of commercial products. Some of them doesn't declare components, some of them vary in time and some can change their components ratio depending on country or other similar stuff. So we decided to remove them.

Any feedback on that point will be useful...

As for previous realeases we still need help.... developers, translators, graphics or simply some feedback.

Thanks to all.
