[IMP] report: reports with custom parsers can be declared in XML files.
[IMP] report: use openerp.report.render_report() instead of LocalService().create().
[FIX] ir_actions: wrong namespace.
[DOC] changelog: give a better hint at how LocalService() can be replaced.
[IMP] ir.actions.report.xml: allow for a smoother transition for reports still declared the old way (in Python).
[IMP] LocalService(): re-allow for a few moment (so addons can be updated a bit later).
[IMP] netsvc: removed unused import.
[IMP] report: remove the print statement upon report registration.
[IMP] ir_actions: removed forgotten print statements.
[DOC] report.
[IMP] netsvc: slightly more explicit warning when using LocalService().
[MERGE] merged trunk.
[REF] ir.actions.report.xml: register_all do not make sense any more:

auto=True reports are looked up in the database for each rendering, so they do
no have to be in the report registry any longer.
auto=False reports will register themselves but at this point
they can be updated to use the new `parser` XML attribute.
[REF] ir.actions.report.xml: renamed ids to res_ids because those are not the self model IDs.
[FIX] reports: now that _register_all() has been removed, LocalService() must be modified to do the lookup in the database too.
[IMP] netsvc: LocalService deprecation now guarded via openerp.conf.deprecation.
[IMP] report: registration deprecation now guarded via openerp.conf.deprecation.
[IMP] conf.deprecation: comment.
[IMP] orm: added a print_report() method.
[DOC] changelog updated to mention the new print_report().
