Conquest 9.0.1 Stable Release

• This is a minor release - most of the changes are internal and
  won't be visible to end users.

• reformat logging output to be more syslog-like

• continue refactoring some of the internal code to make use of C++
  containers and remove dynamically reallocated arrays, add more
  std::string-ification.

• For new users without a .conquest/conquest.conf file, add two
  new default mouse macros:

  scroll up = zoom in (magfactor): "]"
  scroll down = zoom out (magfactor): "["

• tighten up the conquest meta server - detect and log more errors,
  add some more validity checks, be more robust.
