sky-collect needs to include rimestats
Fix build issue in sky-collect. rimestats isn't enabled by default;
created a project-conf for this example that enables rimestats
g/rimestats Fix #183 (short term fix)

This is a temporary fix for #183, so that things can
build cleanly until the issue is fixed properly.

If RIMESTATS_CONF_ENABLED is 0, rimestats.foo will always
read as 0, since RIMESTATS_ADD(foo) doesn't do anything
g/rimestats Provide a macro to read rimestats when enabled
g/rimestats Rename RIMESTATS_CONF_ON to RIMESTATS_CONF_ENABLED
g/rimestats Replace reads of rimestats with RIMESTATS_GET(x)
