Edit of install xml file

Hi Kai,

I've just add update 1 of the file.
Edit of the xml file (version 2.0.1 : 1 because it is update 1 of the version 2.0.x. I will soon add a topic for translators to explain the new rules for numbering the version. For example, in 2.0.4, 2 is the main version, stay the same if no important change in all the coding. 0 is the number for new strings of translation, as it means new options or features. And 4 is the number for update, with bug fix, or else, but with no new strings of translation. So now, all the version will be with 2 numbers for translation packs, the 2 first of iCagenda. But if a change, edit, or correct needed in a translation packs with no new strings, we will number it with the number of this update, so, there, it is update 1 of the finish pack. (will try to explain it better soon! ;-) )
Thanks for you update !
Have a nice sunday,
