Improved bug hunting
* variable constraints
* handling of multidimension arrays
* function calls, execute functions that are in same TU
* improved handling of containers
* several improvements for uninitialized variables check
* improved analysis of for loops

* one more heuristic for ternary operators
* improved data flow for containers

CLI:
* Fixed some addon execution problems when there are spaces etc
