add state absent/present to actions file, copy and template

another solution to adding arg state=absent to template and copy.
However this one adds a perhaps confusing state for a file as present.

Perhaps this can be reworked so a file marked as present can be a file/directory or link.
So the time being I just 'alias' present as file.

template: src=bla dest=ba state=present|absent
copy: src=bla dest=ba state=present|absent
