[WIP] TSD Future

[blakeembrey]

This is the PR for #150. Uses a new tsd.json format (seen in the PR) to handle the updated functionality. Takes future compatibility seriously in that dependencies can resolve transparently between NPM/Bower/TSD.

• Resolve dependency tree from multiple sources (NPM, Bower, TSD)
• Resolve TSD dependencies in child dependencies (tsd.json in NPM/Bower module)
• Implement tsd install using dependency tree and automatically resolving missing deps
• Implement tsd install to prompt for conflicts
• Implement tsd install --implicit by searching, installing and saving dependencies from definitely typed that are currently missing
• Implement tsd search <query> to search and install from definitely typed
• Create tsd init --upgrade to upgrade from old tsd.json format seamlessly (manually blacklist node from being a normal dependency)
• Implement tsd list to show current installed, extraneous and missing deps from dependency tree
• Implement tsd rm <name> to remove a dependency
• Implement --save, --save-dev, --save-ambient, --save-ambient-dev for tsd install <query> and tsd rm <query>
• Implement tsd prune to remove extranuous dependencies (deps found in tsd.d.ts but not listed)

Is this branch available as a build? I'd be very interested in this one

Hi @ciotlosm. There's nothing available yet, but this PR/branch will be up to date with any changes and comments so feel free to watch for anything to say when it's usable. Right now, there's no actual functionality (can't do any commands) but the core resolving logic is there.
