Workbench saving workflow of more than 255 chars does not work

[lucaslaurent04]

If I create a workflow with Workbench and try to save it, it triggers an error because the core_meta.value column is limited to 255 chars.

So when I save, the php class is modified, but the workflow diagram is not saved in core_meta table.

Request from eQual console:
