FIXES#865
- 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.

Convert Python bool type from/to C++/QVariant bool (QVariant::Bool) in
PythonHelper::variantToPyObject and PythonHelper::variantFromPyObject.
This fixes the "override" option and any booleans in the "defaults" list
in grubcfg.conf.
Rename PythonJobHelper ==> CalamaresPython::Helper.
Add QVariant to boost::python::object conversion functions.
Rename some constants in the libcalamares Python API.
