[Rest2web-develop] "none" and "multiple" checks are no more :-)

[Nicola L. <ni...@te...>]

configobj.py
------------

Actually added the RepeatSectionError class. ;-)

validate.py
-----------

Deleted the "none" and "multiple" checks, and good riddance, I'd say. ;-)

Added the None value in Validation.check: now None is an admissible value
for all checks. When specified in the defaults, it affords an easy way to
omit a key from the config without having a real default, making it
effectively optional.


It currently happens that if a section has only scalars with defaults, and
__many__ subsections, it may be omitted from the config, making it optional
too. I like it that way. :-)

I also updated the validate.txt doc, deleting mentions of the "none" and
"multiple" checks, and adding a mention of None as an admissible value for
all checks.

I've been able to complete my use case. I now have a good configspec, and
both a complete and (very) minimal config that comply with the configspec.
I'm satisfied with the results, and have no further feature requests. ;-D

The real test will happen when I integrate it in the code, but that will
have to wait some time. I don't expect problems, apart from the fact that
currently config is traversed with dot (attribute) notation, and all uses
will have to be converted to dict notation.
