Deployment: added Postfix config for email updates
Don't Panic!
cache notaries to sessionStorage
UI: Cache public key lookups for speed
UI: Added cipher- and plaintext caching
Made max incoming email size configurable. Default 15MB.

Note that this *bigger* than the max size that a user can currently send, or that we can store.

When we receive mail, we strip out all content types except text/plain, so a typical 15MB email will still be stored as a small bit of text.
Added hello@scramble.io to front page. Small JS cleanup.
Test Mailchimp signup page: /doc/signup.html

Real updates + blog coming soon
create ~/.scramble directory first time around
reply tries to reply to non-self address.
Email view model cleanup, bug fixes
Removed link to running-a-scramble-server
Fixed issue: tab delimited References header
UI: fix JS bug when sending unencrypted mail
Server configuration: fixed bug loading from file
Reliability: proceed if all but one notary responds

This was previously an error, and is now a warning.

If more than one notary fails to respond for a given address, it's still an error.

If the notaries that respond don't agree on the public key for a given address, that is of course still an error.
