context refactoring: fix `get-relative_url` so that it is really resource dependent (it now uses `get_url`).

Also removed left-over print statements from previous changes.

context refactoring: simplify `ResourceSystem` further

The `ResourceSystem` is no longer a default `IResourceManager` for otherwise unmanaged resources.
The default implementation for `get_resource_url` and `get_resource_description` has been moved in the helper functions `get_url` and `get_description`, respectively.

Added a few API documentation and doctests.

context refactoring: fix the handling of attachments, which was broken by the recent serie of changes.

context-refactoring: remove the `env` from the `Resource` class.

This makes the `Resource` class really light-weight and a bit easier to create.
OTOH, there's no more the possibility to have convenience methods such as `name`, `shortname`, `url`...
Using their replacement functions `get_name`, `get_shortname`, `get_url` is therefore mandatory now, and slightly more verbose as we need to pass the env as first parameter. The corresponding helper functions in the template files of course don't need that `env` parameter.

context manager: r6064 was a bit overzealous, and was fixed partially in r6065 and now completely with this change.

context refactoring: now replace `Resource.name` by `get_name`.

context refactoring: introduce `get_summary` instead of the `Resource.summary` method.

context refactoring: following up to the style change of r6057, introduce get_shortname instead of the `Resource.shortname` method.

context refactoring: typo in the interface declaration for the !ResourceSystem. Good catch from coderanger!

context refactoring: some small fixes
- attachments were not properly tested: attachment view and list work again
- missing import in the code for creating a ticket summary
