Implement default and verbose logging

[end2endzone]

Is your feature request related to a problem? Please describe.
User are complaining that application is too verbose which creates big files. Having too much information printed in the logs make debugging of custom configurations harder.

Describe the solution you'd like
An internal flag should be use to enable or disable verbose logging. When the application is verbose, everything that can be log should be logged.
Multiple verbose logging could also be defined (0 (default), 1, 2, 3, ...). For example, in full verbose mode, the failures for <visibility> and <validity> could also be defined. This would help user understand why a menu is (or is not) displayed.
The property shellanything.verbose.level could be defined in the system as a dynamic flag to enable/disable verbose logging. A menu in ShellAnything's default Configuration could also be created which set/unset this property.
