Remove remnants of old-style macros, as we couldn't support them anyway anymore.

The wiki-macros folder should be kept, though, at least for 0.11, as it now contains a README documenting the need for a conversion to the new-style macros. Likewise, the example macros (!HelloWorld and Timestamp) have been converted as single file plugins, and placed in the new `sample-plugins` folder.

The `sample-plugins` folder could be used for other, small, useful or otherwise illustrative plugin examples.

PermissionPolicy: first part of fine grained permissions for attachments
- use ATTACHMENT_CREATE and ATTACHMENT_VIEW
- the checks for ATTACHMENT_VIEW is now done directly in the `list_of_attachments` macro, not in the individual modules

The check for an attachment related permission is done by checking a specific verb against an 'attachmnent'-realm subcontext of the given context, e.g. `'CREATE' in context('attachment').perm`.

An example plugin demonstrating the new mechanism will follow shortly.

use `urlparse` module to handle conversion between relative and absolute timeline URLs (re #4287)

PermissionPolicy: apply permission checks to individual tickets for the timeline events and search results

PermissionPolicy: use single word permission name for `TicketContext` permission checks

PermissionPolicy: the Ticket module now also uses context-based permissions

The API of most module methods are now using directly a `context` argument.

Make it possible to create a new ticket object out of a `TicketContext` having an unspecified `id`.

PermissionPolicy: prepare the way for permission checks for Attachments
- follow-up to r4569 (i.e. make `TicketContext` really work)
- simplify `Attachment.get_timeline_events`
- fix `Context.__call__(id=...)` so that the realm of the parent is used

Ported r4570 to 0.10-stable (fixes #4546)

add "host" parameter handling to Postgres connection strings for connecting via a socket (fixes #4546, thanks to pacopablo for the patch)

Forgotten to fix the `field-summary` id in the Javascript, after the rename. Closes #4550.
