Add version command

- Add new styling system which works around concept that
  you use tags to request jline styles where tags comes
  from an activated theme.
- There is a default theme with options to add custom
  ones and change it via property.
- Add templating system which uses antlr stringtemplate which
  allows to write output with a template instead of manually
  crafting code.
- Add version command which integrates to Boot's BuildProperties
  and GitProperties. Only version field is visible on default
  and others can be enabled/disable via properties.
- Fixes #352
- Fixes #353
