Python is heavily based on its core data types, and dict is one of the more
important ones. Even classes are basically a wrapper around a dict. This
converts metadata.App to be a subclass of dict so it can behave like a dict
when being dumped and loaded. This makes its drastically easier to use
different data formats for build metadata and for sending data to the
client. This approach will ultimately mean we no longer have to maintain
custom parsing and dumping code.
This also means then that the YAML/JSON field names will not have spaces in
them, and they will match exactly what it used as the dict keys once the
data is parsed, as well as matching exactly the instance attribute names:
* CurrentVersion: 1.2.6
* app['CurrentVersion'] == '1.2.6'
* app.CurrentVersion == '1.2.6'

In many cases, there are times where metadata errors need to be ignored, or
at least not stop the command from running. For example, there will
inevitably be new metadata fields added, in which case a packaged version
of fdroidserver will throw errors on each one. This adds a standard -W
flag to customize the response: ignore, default, or error.
* by default, the errors are still errors
* `fdroid readmeta -W` will just print errors
* `fdroid readmeta -Wignore` will not even print errors

I was wrong - we don't check for trailing whitespaces on lines. That
would have to happen at parse time, not in the linter, so it would slow
things down and would become an error, not a warning. Not really worth
it.
Avoids typos, such as one I just found which was 'strsng' isntead of
'string'. The static analyzer can catch those if they are constants.
Comparing ints is also faster than strings, which adds up in readmeta.
Only keep lists in metadata files in the json format, since they don't
support multiline strings that are readable.
This makes the internal code easier, and a bit faster.
This simplifies usage, goes from
build['flag']
to
build.flag
Also makes static analyzers able to detect invalid attributes as the set
is now limited in the class definition.
As a bonus, setting of the default field values is now done in the
constructor, not separately and manually.
While at it, unify "build", "thisbuild", "info", "thisinfo", etc into
just "build".
This simplifies usage, goes from
app['Foo']
to
app.Foo
