This release fixes a bug and adds a new feature.
First, the -v/--version flag behavior from `argparse` is fixed via a patch to its version action class and now the VersionOption class that already existed is caught in the _main_ method and takes the proper action.
Second, the `Application` class's `main` method was made more generalizable. Now, you can define a class-level variable named `exceptions` as a dictionary of exception types with handler functions. These handler functions should take the exception instance as its only argument and return an exit status.
