Including

• One variable declaration per variable statement (see Rule to limit variable statements to a single declaration palantir/tslint#525)
• Spaces, not tabs
• No space preceding colons
• Double quotes for strings (though, depending on TSLint's behavior on this, we can be flexible.
• No explicit types for inferrable entities
• use namespace instead of module (see Add no-internal-module rule palantir/tslint#517)
• else/catch/etc. on a different line (see Complement to [one-line]? palantir/tslint#88)
• Space before { in interfaces, classes, enums, any sort of attached statement body, or type annotation.
• No trailing whitespace
• Forbid boolean/undefined parameters who aren't named.
• Forbid null

Any other suggestions?
