Fixed windows packaging
- Apply the same principals as pms packaging installers containing JREs (x86 and x64) as well as an installer without JRE
- Re-include image resources used in default 'Detailed' media library folders
- Include the correct resources in core (which will be packaged in pms.jar) and packaging (which will be installed to the installation directory) and delete unused ones
- Updated wrappers to include MLX in names to avoid collision with pms. Increased the Xmx to 1024MB
- Add files to git ignore list

TODO: remove unused properties in packaging(pom.xml once the OSX and linux builds have been fixed
