There is no schema_version 1.4

This prevented your package from being shown in PC.

Please also take a look at the new 2.0 schema ([info](https://sublime.wbond.net/docs/developers), [example file](https://github.com/wbond/sublime_package_control/blob/master/example-repository.json)) and consider adding your package directly to the [main channel](https://github.com/wbond/package_control_channel/) using the new `tags` feature.
