Bug fix with setting message delimiter and string optimizations

verbose off by default
reserve 1k for ourgoing string to prevent allocation slowdown
set the message delimiter in the client to newline to match the servers default (prevents examples from running)
removed some cout loging
converted M_PI to PI to match new OF standard
uncommented framecount incrementor in simulation mode
strings now passed by refrence whenever possible
string concatination via + replaced with += or append in most instnaces
sever continues to send frame updates when a new client connects after all prvious clients had disconnected. Kind of edge case but happends a lot when debugging.
