Colin Walters 4886275df4 ShellApp: Change activation API
Since almost all of the callers of shell_app_activate were using the
default workspace (by passing -1), remove that parameter.

Add a new shell_app_activate_full() API which takes a workspace as
well as a timestamp; previously we might have been ignoring event
timestamps from elsewhere.
