[Toaster] [PATCH 5/5] toaster: clarify the units used for buildstats

[Elliot Smith]

The disk IO value for a task in buildstats is measured in bytes
rather than ms. Modify the "all builds" and "project builds" tables
to reflect this.

Add some notes to the Build model to make it clear which units
are used for each buildstats property.
