Small fixes

In addition to these fixes, you might want to change the capitalization of JS to Js in the name of JSValidate.sublime-settings to be consistent. I was playing with an unpacked version of the plugin and accidentally deleted this file and a new empty JsValidate.sublime-settings was created. You'd just need to run `git mv JSValidate.sublime-settings JsValidate.sublime-settings`. This would require changing the value of SETTINGS_FILE in JsValidate.py but nowhere else; the capitalization is correct in Main.sublime-menu.
