Add "no project" and "no context" option for eary reviewing

[GoogleCodeExporter]

Add "no project" project on the bottom of the projects perspective. This way we 
can easily review all tasks without a project, and assign one if needed.

Similarly, add "no context" context on the bottom of the contexts perspective.

It is easy to review tasks without project and context because they appear in 
the inbox. Tasks that have just a project but not contex and vice versa are not 
that easy to find. This would make it easier to review these tasks.

Can you specify the behaviour in conjunction with the view's settings? It's not 
obvious to me hat should happen if the implicit [no XYZ] container does not 
meet the view's filtering rules.

Another approach to this issue could be an individualizable inbox behavior. 
That is:
There is an option "behavior" in the view settings of inbox. This option 
consists of four alternative behaviors: "no project and no context" (standard, 
used right now), "no project", "no context", "neither project nor context" (was 
used some time ago as behavior).

I'm not sure what the difference between "(no project) and (no context)" and 
"neither project nor context" would be, since I would translate "neither 
project nor context" to just that. I think "(no project) or (no context)" would 
be an alternative, which I would descibe as "either no project or no context".

Regarding your suggestion to allow additional Inbox view settings, I feel it 
would be nice to maintain the current approach in which all view options are 
available in all view's settings, even if some are grayed out in some views 
because they're fixed.

My mistake. I meant "(no project) or (no context)" and "(no project) and (no 
context)" as options. The latter one is used right now to select the actions 
displayed in the inbox. Some time ago the first one 

Also look at http://code.google.com/p/android-shuffle/issues/detail?id=34#c9 
Issue 34 was about actions without projects, but the comment gives some 
suggestions about contexts too.

[quote (shortened)]
* How about setting the default context to "Inbox" or "To process"?
* Make the default project "None" and give it no other implicit meaning that 
what it
is: does not say anything about the status of that task.
* Make it possible to have "None" be a valid choice for context as well. And 
again:
it should mean just that and be treated exactly the same as any other context.
 That would make it clear which actions still have to be moved out of the inbox, and
it gets rid of the dependency of assigning a project.

Interesting indeed.

I must admit I'll have to think about this, since my original intention was 
simply to point out that the suggestion appeared not very straightforward with 
respect to the current Shuffle features. I was by no means intending to suggest 
I had a concept available. ;)
