Subject: [PATCH] Handle reset form action
Add new type of action EV_LINK_ACTION_TYPE_RESET_FORM for EvLinkAction
together with properties "reset-fields" and "exclude-reset-fields".
The properties controls which fields are reset and are set in PDF document.
This commit extends EvDocumentFormsInterface with new method "reset_form".
Check for poppler 0.90.0 or higher when calling its methods for resetting
of forms.
Issue #46
