Updated change log for 5.4.10.
Removed the sim-mode accelerated clock.
Always set the suite info update flag if a task state changes.

This fixes a minor bug in simulation mode: the suite state summary would
not be updated for 'running' if nothing else was happening at the time,
because in sim mode this state change is not caused by an incoming task
message (which does always result in a state summary update).

Don't create a new state dumper on suite reload.

Since 9d5b7e9 we were creating a new state dumper on reload, but not
giving the new instance a reference to the task pool, which resulted
in truncated state dumps (no task states).
Added a test for restart after reload.
Took cylc cycletime validation out of lib/parsec.
