[Moose-dev] DistributionMap wizard improvements

Hello,

I Improved the distributionMap wizard on several points: => no long computations anyMore. Should be usable with large models => adding some 'conditions' before leaving the first pane. Avoid to end with exceptions: - if properties are not well entered - if properties specified are not 'computable' for this model => refactored/cleaned code/ Divided into shorter methods/recategorized Looks at least cleaner than before

It should fixe the problems recently experimented when trying all moose menus
