[teampractices] Phabricator terminology change (blocking->subtasks)

[Joel Aufrecht]

Should we make (or find and join) a request that they provide a way to
differentiate between the two cases?  Possible uses:

different display in the UI
use in data analysis, e.g., summing up tasks by summing up their subtasks
(and not dependencies)
