Update to latest Meteor and other dependencies.
Apparently Meteor is now nonsensically rewriting URLs in CSS.
FUSE -> Cap'n Proto bindings. Read-only for now.
Merge branch 'master' of github.com:kentonv/sandstorm
Improve FUSE caching and other tweaks. PS this fuse stuff is for a build tool.
WIP tool to run apps in 'dev mode' and auto-detect dependencies.
Make it easier to install custom builds, e.g. for local testing.
Continue work on 'spk dev'.

App is now being FUSE-mounted into the daemon's namespace and the front-end is being notified; all that's left is for the front-end to actually react. But I need a better way to do front-end development while connected to a real Sandstorm installation...
Make it easier to run a dev front-end against an installed Sandstorm instance.
'spk dev' successfully registers dev apps with server. Now just need to capture output.
Easy port mostly working.
