Run initial sync at startup and add verbose flag

[lokijuhy]

New Features:

• code_sync now runs an initial rsync upon startup before running in watch-for-changes mode, so that changes are synced right away.
• Added a verbose flag that prints the rsync and watchmedo shell commands for help in debugging.

Bugfixes:

• Fixes [BUG]: rsync error w/ AppleInternal error #3, where using command line args instead of the project registration did not work (because the port number was set as the local dir)
• Fixes issue where local dir paths were not expanded, and did not work if contained ~
