Update tsconfig.json schema on SchemaStore for new commandline options for TypeScript 1.5

[mhegazy]

here is the schema: http://json.schemastore.org/tsconfig
here is the store: https://github.com/SchemaStore/schemastore

and here are the new flags:

• --rootDir
• --module umd
• --module system
• --noEmitHelpers
• --inlineSourceMap
• --inlineSources
• --newLine

The module value for the systemjs format is actually just system right now, isn't it? (Noticed this misprint in the roadmap as well.)

[mhegazy]

thanks @kfranqueiro for the correction. fixed.

I will hold off on this until we ship 1.5 to avoid confusion.

Didn't see this issue, so I already submitted a pull request to the schemastore repo.
