This allows to parse PayPal balances which includes both symbol and letters, for
instance "$ 42,00 USD".
Also, it does not require adding any new symbols to the regular
expression.
It might break modules, though numerous cases were tested.
1) Rename it to ICapGauge
2) One gauge can have more than one sensor (a flow and
a level for a river, or temperature and humidity for
a wetter station)
3) Add/remove/rename fields to be more general
Most backends don't set it nb_messages and no application used it.
No backends set nb_unread and only one application tried to use it.
This should help avoid useless fillobj() calls in some cases.

It is unused, and no backend implemented it — so it was wrong to have it
in the function signature.
It also does not seem very helpful, we have get_threads() if we want to
do something advanced with treads.
fixes#825
There is now a "latest" collection (or "latest_nsfw").
The feature didn't look much used, since it didn't work on many
backends.
Using collections will make it easy to support other things
like most viewed, featured, etc.
As a bonus, I added tests for every backend with the feature.
I used autopep8 on some files and did carefully check the changes.
I ignored E501,E302,E231,E225,E222,E221,E241,E203 in my search, and at
least E501 on any autopep8 run.
Other style fixes not related to PEP8:
* Only use new-style classes. I don't think the usage of old-style
classes was voluntary. Old-style classes are removed in Python 3.
* Convert an if/else to a one-liner in mediawiki, change docstring style
change to a comment something that wasn't really appropriate for a
docstring.
* Unneeded first if condition in meteofrance
Don't force objects to have an id, especially since that id was
incorrect. "plap/plop" would have the same id as "plop", i.e. "plop".
We don't rely on the id for handling Collections anymore.
Change to use more unique property names.
Change the display, instead of using '*', we use '~', and there is no
"Collection" header anymore.
Updated formatters could use that way of showing the object is also a
collection too.

Handle and use exceptions.
An example is provided with the redmine backend (not very useful
though). If you cd into the project title instead of the id, it is
accepted and the path is corrected.
