youtube-dl is great for finding the video url and more up-to-date than
our code so let's use it.

Search hasn't really changed if we don't use the XML API. I didn't
bother to check whether the XML API still worked, that API wasn't
necessary for search and download to work.

I dropped the whole category and CapCollection stuff because it seemed
buggy. No idea if it can be repaired easily, but at least now the module
works for basic stuff. Collection can be repaired later anyway.

Since Python 2.7 is the minimum version supported,
collections.OrderedDict is guaranteed to exist and there is no need to
reimplement it.

/ set a default test config in case no-one exists

The json no longer lists codecs but access methods (progressive, hls, dash).

We prefer progressive and degrade to hls if required.

For now we take the first stream for progressive, which seems to be the best quality.

TODO: handle selecting wanted quality

        allow to browse categories and channels

weboob.tools.browser -> weboob.deprecated.browser
weboob.tools.parsers -> weboob.deprecated.browser.parsers
weboob.tools.mech -> weboob.deprecated.mech
weboob.browser2 -> weboob.browser
weboob.core.exceptions -> weboob.exceptions

Also, the new tree for browser2 is:

weboob.browser: import weboob.browser.browsers.* and weboob.browser.url.*
weboob.browser.browsers: all browsers (including PagesBrowser and LoginBrowser)
weboob.browser.url: the URL class
weboob.browser.profiles: all Profile classes
weboob.browser.sessions: WeboobSession and FuturesSession
weboob.browser.cookies: that's a cookies thing
weboob.browser.pages: all Page and derivated classes, and Form class
weboob.browser.exceptions: specific browser exceptions
weboob.browser.elements: AbstractElement classes, and 'method' decorator
weboob.browser.filters.*: all filters

They bring nothing of value (we never use import * anyway) and introduce
a maintenance burden.

The __all__ that I left might not be very useful either but at least
they are not a pain to maintain; they are also used by pyflakes in some
cases.
