Needed refactoring of submit manuscript flow.
Checks are run via the forms. Also, the copying
of data from old submissions is done via forms.

All this functionality is removed from the model.

All required actions are determined and saved in `submission.cycle`
now. The actions required are determined at initialization of
the submission. Different cycles now possibly can have different required
actions. All template logic to determine required actions is removed
from the codebase.

`Published` and `resubmitted` submissions dissapeared in the public
search results. They're back in the results as they were too strictly
filtered.
