[jed4] Add extension restrictions

[JazParkyn]

The main change from the current system is that a free, paid and cloud service distribution types of the same extension will be submitted, managed and viewed on the same page.

Add extension view to only allow users to add one of each distribution type (free, paid, cloud service) for each extension.

#__jed_extension - contains the information shared between the distribution types
#__jed_extension_detail - contains the information about the specific distribution type

A user must select at least one distribution type, and cannot have more than one of each type.

A file upload will be required for each type selected, and will eventually be run against the JED Checker

The component should check the user’s account for any pending issues. The component should prevent submissions if:

• the user has 3 pending submissions.
• the user has a suspended account.
• the user has any unpublished listings for any reason other than UR5 (per developer request).

Submission checks:

• All tests currently present in JED
• Pass JED Checker against all files uploaded
• Match Listing Name against install name
• Reserved Words should be accepted (eg. Joomla, component, module, plugin, free, paid, etc)
• Check to see if the alias for the extension already exists

Please see the spec document for further clarification on this process - see: Front-End Submission Process

If it passes, continue.
If it doesn’t pass, display issues from checker to user.
If it doesn’t pass, the user has the option (via checkbox) to bypass the check and describe why the submission is valid. In this scenario, the submission will be placed in a manual review queue.

The possibility of auto populating some fields using data from the extension’s XML install file should be reviewed.
