Run/Debug profile creation

Hi, group,

when I was inspecting how Eclipse manages run/debug stuff, I noticed 
that they implemented helper actions, which allow the user to quickly 
create a profile.

* Run/Debug actions in the main toolbar (menu) are context-aware. They 
are enabled for project, file or a class.

* There is "Run/Debug As" submenu in the action's presenter, items of 
the submenu correspond to profile types known to the IDE.

* When an inappropriate type is chosen, the action is rejected, i.e. a 
message box "The selected class does not contain a main() method" appears.

Note: This approach moves the penalty for discovering whether an object 
is eligible for run/debug action of a particular type from the object's 
appearance. It moves the penalty to the time the "Run/Debug As" action 
is run by the user. The usual counter-measures like progress bars can be 
then used to give fast UI response.

* In the case of a project, or a package, the object's contents is 
searched for items that can be run with the particular profile type.

* When the selected thing matches, the user is presented with pre-filled 
wizard of a new profile. When confirmed, the new profile appears in the 
profile list.


Other things to note:
* Both "Run" and "Debug" have a history list of last run profiles.

* A profile can be marked so that it should appear among Run/Debug 
favourite items -- the Run/Debug history starts with the favourities.

* A profile can be selected as favourite for Run or Debug independently

Cheers,
