zen startup hardening (#49)

- Feature: `zen up` command improvements
	- --`port` allows you to specify a base port when starting an instance
	- --`base-dir` allows you to specify a base directory for the zenserver executable if it is not located next to the zen.exe executable
- Feature: `zen down`
	- --`port` allows you to specify a base port when shutting down an instance
	- --`base-dir` allows you to specify a base directory for the zenserver executable if it is not located next to the zen.exe executable
	- --`force` if regular shutdown fails it tries to find a running zenserver.exe process and terminate it
	- If it fails to attach to the running server it now waits for it to exit when setting the RequestExit shared memory flag
- Improvement: zenserver now checks the RequestExit flag in the shared memory and exist gracefully if it is set
- Improvement: When adding a sponsor process to a running zenserver instance, we wait for it to be picked up from the shared memory section to determine success/fail
