Fix patch renderer unit-test failures (accomodate line number anchors)

PermissionPolicy: clean-up Attachment module
- added an !AttachmentContext
- removed request related stuff from the Attachment data model class
- updated the attachment: TracLinks provider to use AttachmentContext
- updated WikiMacros to use AttachmentContext

Applied patch for #4558.

Simplify the about page: show system information and configuration all on the same page, ''if'' the user has `CONFIG_VIEW` permissions.

PermissionPolicy: second part of fine grained permissions for attachments
- converted the !AttachmentModule
- check for ATTACHMENT_DELETE, but dropped support for its equivalence with 'ADMIN' permission on the parent context; this eventually needs to be re-enabled.

The example plugin (sample-plugins/authz_policy.py) has been updated to accept simple verbs instead of full permission names (e.g. DELETE instead of ATTACHMENT_DELETE).

remove tab indentations added in r4451

Updated to [http://jquery.com/blog/2007/01/14/jquery-birthday-11-new-site-new-docs/ jQuery 1.1].

PermissionPolicy: add a sample plugin for the IPermissionPolicy interface. This is the one I was using for testing r4586 and for that I've added support for attachments to Alec's prototype.

PermissionPolicy: merged latest changes from trunk [4564:4587/trunk]

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.
