Fix _group_lines for #4336, round two

PermissionPolicy: fix `Context.from_resource`

The Wiki diff view was not working proper as the `WikiContext` was reconstructed from the `page` resource. This worked partially but omitted the version information. So we need a generic way to update the context after a resource is bound to the `Context`.

PermissionPolicy: introduce a `TicketContext`

Plus tweaked the resource description related methods on `Context`:
- `name`, gives a non ambiguous name to the resource targeted by the context; there's no more a ''compact'' optional argument, but
- `shortname`, gives a non ambiguous short name to that resource

PermissionPolicy: fixed the `Context.self_href` to work properly when `Context.version` is used.

Also introduced a few resource description related methods on `Context`:
- `name`, gives a non ambiguous name to the resource targeted by the context
- `summary`, gives a more detailed information about the targeted resource

PermissionPolicy: simplified the `Resource.version` specification.

Now, `None` is used to specify the latest version of a resource, in accordance to existing conventions for Wiki pages and the versioncontrol subsystem.

Also:
- the `__call__` method has been fixed to create Context instances of the appropriate subclass according to the given the `realm`.
- restored the doctests for the Context class.

PermissionPolicy: Simplified resource system. Renamed `IResourceMapper` to
`IContextProvider` to reflect its new purpose.

PermissionPolicy: also merged [4563] (blame in scoped repos fix)

PermissionPolicy: merged with trunk@... (blame branch integration -> addition of ''version'' information in the Context)

Fix for the blame feature in case a scoped repository is used. Thanks to Manuzhai for reporting the issue and suggesting a fix.

PermissionPolicy: init svnmerge properties for facilitating merges from trunk
