Added RemoveComments package

[junliu111]

• I'm the package's author and/or maintainer.
• I have read the docs.
• I have tagged a release with a semver version number.
• My package repo has a description and a README describing what it's for and how to use it.
• My package doesn't add context menu entries. *
• My package has key bindings. **
• Any commands are available via the command palette.
• Preferences and keybindings (if any) are listed in the menu and the command palette, and open in split view.

I added a simple package used for removing all comments in the current file based on syntax highlighting.

There are no packages like it in Package Control.

Remove key bindings, instead add instructions on how to add your own.
