no privileged project member of State
no separation of Command and Apply, so no pre-filtering on State
use entries in State attributes map instead of mixing in traits to project object:
HistoryPath, Logger, Analysis, Navigate, Watch, TaskedKey
rework Navigation to be standalone instead of mixin
add syncTask task constructor and copy-resources/copy-test-resources instances
add console-quick, test-console, console, test-run
add IntegrationTest trait
make Context available through 'context' task
update 'last' and 'show' to use Context to retrieve task by name
drop SingleProject (superseded by Project)
add TaskGroup to be able to inject groups of named tasks
fix watchPaths missing flat sources
proper logging in a few more places, such as compile
