Support for synchronous events (PR #841) 

Switched Mockingboard/6522 Timer interrupts & Mousecard's VBlank interrupt to use synchronous events.
This is a linked-list of ordered timer-based event, where only the head of the list needs updating after every opcode.

/* Description: Synchronous Event Manager
*
* This manager class maintains a linked-list of ordered timer-based event,
* where only the head of the list needs updating after every opcode.
*
* The Nth event in the list will expire in: event[1] + ... + event[N] cycles time.
* (So each event has a cycle delta expiry time relative to the previous event.)
*
* A synchronous event is used for a deterministic event that will occur in N cycles' time,
* eg. 6522 timer & Mousecard VBlank. (As opposed to async events, like SSC Rx/Tx interrupts.)
*
* Events that are active in the list can be removed before they expire,
* eg. 6522 timer when the interval changes.
*
* Author: Various
