CmdAccess: discard the InvocationTrail concept

after extended analysis, it turned out to be a "placeholder concept"
and introduces an indirection, which can be removed altogether

- simple command invocation happens at gui::model::Tangible
- it is based on the command (definition) ID
- instance management happens automatically and transparently
- the extended case of context-bound commands will be treated later,
  and is entirely self-contained

 ''Lumera decides to take the latter approach'' -- resulting in a separation between immediate low-level UI element reactions, and anything of relevance to the workings of the application as a whole. The widget code embodies the low-level UI element reactions and as such becomes more or less meaningless beyond local concerns of layout and presentation. If you want to find out about the //behaviour of the UI,// you need to know where to look, and you need to know how to read and understand those enablement rules. Another consequence is the build-up of dedicated yet rather abstract state tracking facilities, hooking like an octopus into various widgets and controllers, which might work counter to the intentions behind the design of common UI toolkit sets.

-An invocation trail represents one specific path leading to the invocation of a command. It is a value object (handle), and it serves as the interface used by the UI-Element to retrieve or supply the arguments and finally to prepare the invocation message(s). But while the invocation trail is generic to some degree, the entity to trigger the command invocation needs explicit and concrete knowledge about the circumstances involved into this invocation. Simply, because in some cases, very specific information needs to be provided as argument. For example, a widget just happens to know that the setting of a specific slider will be what becomes a likewise specific argument.
+Thus an invocation trail represents one specific path leading to the invocation of a command. In the current state of the design, this is a concept; initially it was meant to exist as object, but this approach turned out to be unnecessarily complex. We can foresee that there will be the somewhat tricky situation, where a command is ''context-bound''. In those cases, we rely on the InteractionState helper, which is to track {{red{planned 4/2017}}} an enablement entry for each possible invocation trail. Basically this means that some commands need to be prepared and bound explicitly into some context (e.g. the tracks within a sequence), while enabling and parameter binding happens automatically, driven by interaction events.
