config not completely saved in browser.py

[Lionel Dricot]

handling of config in browser.py is a complete mess.

Currently, some value are not saved, other are not restored and the whole config is overwritten when closing the browser !!!

A refactorization is needed in order to make this work :

- collapsed state should be remembered for both tasks and tags
- size of the closed task pane should be remembered.
- the whole config['browser'] should become config (the browser should receive as argument config['browser'])

I completely agree that we'll need to refactor the browser.
I think config should be handled by the CoreConfig object. That doesn't need to be passed as argument, everything can have access to it just by creating an instance of that (it's a borg, every instance is really the same one).
Also, private_config has to go (I don't even know if it's still there.

Fixed in rev. 924 (mostly, the collapsed state is not restored but this is a liblarch-gtk bug, not a config one)
