Fix missing semicolons

npm module `typescript` of version 0.9.5 failed to parse `meteor.ts.d` due to missing semicolons those are fixed in this PR.

`typescript` still fails to parse `MeteorEventType.Value` enum though. Would like some help with that if anyone wants to keep this file parsable by `TypeScript.Parser().quickParse` since I am not experienced with TS in general.
