Improving dt's UI

[Ivan Glushkov]

Hello.

Let me connect to your dialog.

David, i've looked through your patch, it really good idea, i like it!
It seems that David wants us to add some new realization of entering
values into the issue (analog of UI.Menu). As i understand he suggests
not to select some item from the menu (in several steps, one after
another), but to insert them in $EDITOR.
I suppose it can be made without removing our current functionality.
We should just add new level of abstraction "choosing version from a
list". And have two implementation of that new level, choosing the
needed one from configuration.

If user likes to work in shell, he would prefer to use our current
implementation, if he wants to use $EDITOR - it is easy.

Also i propose to use some sort of comment in $EDITOR.
For example, you could get the following, when running ./dt new

Added-by: gli
Category: dt/dt -- dt/dt, dt/ui, dt/tools
Reported-for: 0.3  -- 0.3, 0.4, 0.5
Due-in: 0.4 -- 0.3, 0.4, 0.5

where current value is the "default" value from username,
etc/categories, etc/versions, respectively
and after comment sign "--" we can see available values.

David, do i correctly understand your proposition?

Ivan.
