Bug description:
After clicking Analyze -> Cppcheck (Current Project), the Cppcheck tool view opens, but it's empty and does not say that analysis is in progress which is very misleading.
The fix adds notification messages to Problems View:
- At the start of analysis: "Analysis started..." This message will be removed with first problem report.
- At the end of analysis (if we doesn't have any problems): "Analysis completed, no problems detected."
For both messages we set current analysis path as problem location.
