Migrate to contexts dependencies/relations from weights
When the project started I decided to use “weight” for contexts sorting in queue because it was easier... Now I needed to change all weight to “normalize” them. Besides if users begin write their own contexts there will be conflicts in weights. So now it seems better to use dependencies.
This means that “weight” member is to be removed and replaced with two or more members, e.g.:
... after => [ 'Number', 'YesNo' ], before => 'Task', requires => [ 'Number', 'YesNo' ] ...
