Port from GObject to GLib

[rhl-bthr]

While I have made the changes discussed in https://github.com/orgs/sugarlabs/projects/5, please mention if I have missed any

Thanks. Reviewed to 7af77eac.

• [ ] in general, function argument lists that were indented under the first argument are no longer indented,
• [ ] extensions/cpsection/aboutme/view.py needs an import,
• [ ] extensions/cpsection/backup/backends/volume.py has a GObject.GError that can most likely change to GLib.GError, and then because no references remain, remove the import of GObject,
• [ ] extensions/cpsection/datetime/view.py needs an import,
• [ ] extensions/cpsection/frame/view.py no longer needs an import of GObject, but needs an import of GLib,
• [ ] extensions/cpsection/keyboard/view.py incorrectly calls GObject.GObject.__init__ in LayoutCombo leaving the Gtk.HBox parent class uninitialised, (not your doing, but it is a reference to GObject),
• [ ] extensions/cpsection/language/view.py no longer needs an import,

... at this point I got bored and figured I could just use flake8 twice and compare,

git checkout master
python -m flake8 . > flake8-master
git checkout port-gobject-glib
python -m flake8 . > flake8-glib
meld flake8-master flake8-glib

Much nicer. Leave it to you?

(p.s. there are plenty of flake8 issues already, so the compare output method can help instead.)

Thanks. Sorry for not verifying earlier.

Fixed all instances.

Thanks. Reviewed 93095ce using flake8 comparison.

extensions/cpsection/aboutme/view.py:368:13: F821 undefined name 'GLib'
extensions/cpsection/aboutme/view.py:369:26: F821 undefined name 'GLib'
src/jarabe/main.py:62:1: F401 'GObject' imported but unused
src/jarabe/view/keyhandler.py:20:1: F401 'GObject' imported but unused
src/jarabe/view/keyhandler.py:167:13: F821 undefined name 'GLib'

Also several argument list indentation changes, and a few line too long.

Thanks. Running flake8 didn't show these errors for me. Diagnosing.

Fixed the instances and set PEP8

Thanks. a5f87d1 is nearly there, though keyhandler.py still has a GObject import unused (F401).

c0d53eb is more than is needed, and I don't have time to review it, my preference is to omit it, as there's the pending python3 branch to merge with eventually.

As for why flake8 didn't show them for you;

• make sure you are running the python2 version of flake8 (python2 -m flake8 .),
• make sure you don't have a .flake8 file higher up in your directory tree or user home directory, and;
• you have an E402 ignore in a .flake8 file at the level of this repository (because otherwise several reports are omitted).

Thanks again. Please re review
