Variant groups

[kronenthaler]

Attempt to solve #113. Needs confirmation from @st3fan.
How to use:

# load project as usual
project.add_file('en.lproj/<file1>.strings', ...)
project.add_file('en.lproj/<file2>.strings', ...)
project.add_file('en.lproj/<file3>.strings', ...)

Maybe i will add a helper method to add a full folder later on, after confirm that this works as expected.

I've created a pull request that fixes some issues with this: #124 (I apologies if I've done this incorrectly, I'm a bit of a GitHub newb!)

Sorry for not responding, I will try to give this a go next week.

I'm trying to do the same thing as st3fan here. I have a bunch of InfoPlist.strings in different language_code.lprof folders where language_code can be de, fr etc and I want to add them to my project. I have tried the following:

from pbxproj import XcodeProject project = XcodeProject.load('./myProject.xcodeproj/project.pbxproj')

project.add_file('./de.lproj/InfoPlist.strings', force=False)

project.save()

However, after executing the above the InfoPlist.strings file was not added. Using diff shows no changes were made to the project.pbxproj file.

If I instead set force=True in the add_file function then I get the following error:

Traceback (most recent call last):

File "import.py", line 4, in <module>

This PR is very incomplete and buggy. It needs more work. I will close and reopen when better solution comes.
