Use sensiolabs/ansi-to-html to parse the build logs.

Added an AnsiConverter helper.

Use the AnsiConverter in the email and page templates that display the build log.

Use a dedicated stylesheet for the ANSI converter.

It can be customized.
It can be inlined in the notifications.

Do not use ProphecyTestCase when not needed.
