added basic README files for all components

    heavily inspired by http://fabien.potencier.org/article/49/what-is-symfony2 and the official Symfony2 documentation
fixed README for Console
cosmetic tweaks
added READMEs for the bridges
added some more infos about Config
typo fix
[HttpFoundation] Cookie values should not be restricted
Oracle 10 issues

I've changed Schema.php to not use Restrict on delete/update since
oracle report it as missing keyword. Both restrict and no action on
oracle seems to be redundant and used by default. So the output query
can't use it. I've also changed Schema construct to accept a
SchemaConfig parameter. InitAcl was changed to pass on new Schema a
SchemaConfig generated by SchemaManager, I did that because acl command
was generating names with more than 30 characters and Oracle doesn't
accept, this seems to solve the problem and init:acl works properly.

is it still needed after https://github.com/doctrine/doctrine2/commit/619a31913a4f5952248a0b909a25c2020619c29f ?

Yes i think. It doesn't cost anything to have this check and gives a much better error message than the generic Doctrine one.

but it gives it only in one case (id missing). It will not handle the case of incomplete composite key which will go to the doctrine error.

I wasn't really sure about the correct approach. This one is very minimalistic and following the existing concept of not duplicating nodes of the same name, but only storing multiple values for the same node. If you think that should be changed, let me know. Hints appreciated.

Thanks
