Tackle some TODOs.
Host OpenSans locally rather than source from Google servers.
Update license file, relicense implementation as AGPL.  (The API is still BSD; apps do not need to be open source.)
Add Joyent HTTP parser library to source tree.  (Used by legacy-bridge.)
Close some more TODOs.
Implement signup invitations.
Register custom protocol handler for installing sandstorm apps.  But Firefox is obnoxious about it.
Various cleanup.
