Generated header files for Qt4 .ui files with cmake

[Nicolas Goutte]

Before I forget again to discuss this subject (for the umpteenth time), I 
write quickly this short email.

In Qt4's .ui files, the user-visible strings are now in the header files and 
not in the cpp file anymore. Therefore the -tr tr2i18n parameter must be 
given to uic when generating the .h file.

I had done this for unsermake however for cmake it was still wrong. Therefore 
somebody should probably look at it. (Sorry, I have no time for implementing 
it and now I have even not any time to check if it was fixed in the meantime.)

Note too that I do not remember if I have checked the behaviour of uic3 files, 
so perhaps somebody should look about that too.

I am sorry for the inconveniences.

Have a nice day!
