Change Log 5.8.3

• manager: use user-friendly app names (fix to work w/ 5.4.11)
• MGR: Possble fix for the Simple GUI messages dialog?
• manager: don't prepend "(Activities suspended by user)" to result status. There is no longer a notion of "activities"
• MGR: Copy missing source file from HEAD branch for Frank Weiler's pie charts updates.
• MGR: Streamline the message dialog sync operation a little bit.
• core client: lots of debugging messages for cpu_sched (may remove later)
• Manager: check for ERR_DB_NOT_UNIQUE, not ERR_NONUNIQUE_EMAIL
• Update libCurl to 7.16.0 and use sync name resolves instead of async name resolves.
• core client: fix a bug that could cause computation to stop.

• The problem: if we suspended a task by sending it a <quit/> message, we were changing its scheduler state to CPU_SCHED_PREEMPTED but not changing its task state (PROCESS_EXECUTING). If, for some reason, the process didn't exit right away, the scheduler would treat it as still running, since it builds its "currently running" list based on task_state.

• Solution: the scheduler shouldn't be looking at task_state. Use scheduler_state instead. It's still a mystery why the app wasn't quitting.
