Allow Extension to Versioning format

[vickyokrm]

The application version format currently supported is MAJOR.MINOR.PATCH which is also validated. However, allowing additional extensions such as:

             | <version core> "-" <pre-release>
             | <version core> "+" <build>
             | <version core> "-" <pre-release> "+" <build>

could be useful in scenarios where for example 'git hash' together with version to be displayed.
