[QBS] Join some locale into one QM with 3th name

[alex at obukhoff.su]

Hi, 

 I have several projects with a common library with its own file transfer. 
During building I combine multiple ts files into one qm.  Visual Studio build simple call CMD file having the following content:
<code>
lrelease "..\libs\Project1\src\locale\Project1_en.ts" "..\Project2\common_en.ts" -qm "build\locale\Project3_en.qm"
</code>

How to realize it on the qbs.

I try to use next code, but result not satisfy me.

<code>
                Product {
                               name: "Project3Translations"
                               type: "qm"

                               files: [
                                               "..\libs\Project1\src\locale\Project1_en.ts",
                                               "..\Project2\common_en.ts"
                               ]

                               Group {
                                               fileTagsFilter: product.type
                                               qbs.install: true
                                               qbs.installDir: "locale"
                               }
                }
</code>

Result of this qbs – 2 files Project1_en.qm and common_en.qm
But I need 1 file Project3_en.qm !
