[Lazarus] LazDataDesktop duplicated language translation files

[Marcelo Borges de Paula]

Well, before adventured myself, helping Lazarus with translations, i did some research about how things were done in this matter.
Seems that majority used this method, so i followed it.

Some considerations:

- Using "i18n option enabled" you have two different behavior of IDE automatic language generation:
   1) Projects: IDE generated .po file with project´s name, which concentrates all resources from all files in project.
   2) Packages: For every form in package, a correspondent file (.lrt) is generated and a correspondent file (.po) file is generated. 
                       This could end with a bunch of files in language directory, each one requiring translation. Example: If a package generates 4 language files, for each 
                       language you got 4 files. So if you have 10 supported languages.....

- Concentrate all resources in one .pas file gives you more centralized control over that strings. This is not the case with "i18n", since IDE can generate resources from
  .pas where they are declared. So you know that that string exists, but you will need to do a search in files to locate it. This is more simply to do in one file.

- I tought that having one method in mind is better than having to remember that for projects i need to do one way, and with packages another way.

Maybe it´s a good opportunity to discuss some standards about this matter. There is a lot to do in this field. Reach a common sense may avoid big headaches in future.
