Addition of windowless (javaw) option

[SotirisVas]

Added a new option to call "javaw" instead of "java", only for Windows as Unix does not need this utility.

Fixes #65

Proposed Changes

1. Add new option for windowless
2. If true, javaExe becomes javaw
3. Check if caller platform is actually Windows, if true then use javaw, used for cross-platform compatibility
4. Added changelog entry and documentation for the option
