Show success or failures for heroku builds

[schneems]

Can we list pass/fail status in the UI for heroku builds? Maybe a color code, or put a unicode ✔ and ✖ in a column. This would let me scan at a glance the most recent passing build (or most recent failing build).

Another thing that might be helpful is to also list the release number, that way I could easily run heroku releases and see if something changed between version numbers.

The version will show in yellow/red/green depending on the build status.
This could definitely be improved though.

Displaying the release number is going to be trickier though, as it requires one additional request per build, which is going to slow down the request a lot.

The request number is less important. Maybe a flag for it like -x or something. But it's not critical for now
