Added support for workflow validators checking attachment properties

New in this release

Added support for workflow validators checking specific categories for presence of attached files or verifies that attachments were uploaded by a specific user, by users from a specific group or by users having a specific project role.

Now you can easily customize workflow transitions and add validators checking for attachments meeting the appropriate criteria.

Now JIRA users will not be able to execute transitions if validation of attachments fails.
