- remove Job.gettextPath
- add libcalamares.utils.gettext_path()
- add libcalamares.utils.gettext_lang()
- modify examples in main.py
- add some gettext debug-output from dummypython
- correct namespace mis-labeling
- provide two forms of GlobalStorage
- regular use, has a JobQueue with storage
- testing use, creates GlobalStorage separately, provide
independent access to that for Python.
This allows us to make GlobalStorage a QObject, with disabled copy
constructor. And thanks to this change, GlobalStorage now emits
changed() every time an insert or remove is performed.
