Changed version number of the xsd definition file.
Begin AOSL 2.0 Draft 1
done #13 : renamed in xsd story->storygraph, stage->node, move->transition.
Updated tests to 2.0 tag names.
We use tabs.
Removed group_change_extension.
Info is already plural.
Merge branch 'develop' into feature/AOSL-2.0
Renamed documents in lower case to help with future html generation.
Simplified specs doc name.
Renamed specification file to be more explicit and with version name.
Moved AOSL 1.0 tests in a version-specific directory.
Fixed AOSL version in specification doc.
Fixed: code not displayed properly in understanding doc.
Decided against having several versions of the specifications and tests in the same repository revision.
Tags will solve this problem and it will easily be possible to get different versions from github or other places.
