Enable Autopilot all the time

(Copied straight off his comment from "Wings Gravity Fix for Bloodbath.")
Want to use autopilot on maps that disable it?

In src/bzflag/clientCommands.cxx, find:
---
if (BZDB.isTrue(StateDatabase::BZDB_DISABLEBOTS)) {
hud->setAlert(0, "autopilot not allowed on this server", 1.0f, true);
return std::string();
}
---
Remove it.
