At random, if you use 'give ship' while your ship is moving, you can be trapped in a state where you cannot turn or move in any direction. You are still given the new ship, however, and if you use 'give ship' a few more times, you can recover from the problem.

Leaving this as low-priority since 'give ship' is technically a cheat. Setting this as category 'src' because the cause is unknown.

Since the 'say' chat command is now used to chat in the current zone,
it become useless on dedicated servers because the console does
not have a current system.

There are several ways to solve this:
- Have say behave like shout
- Add an extra parameter to say to indicate the zone to chat in
- Provide a way for the console to set the current zone

Right now the client keyboard input code is hardwired
to a US-QWERTY layout. It should use the native keyboard
layout of the user.

At the same time, the code should be tested for UTF8.

Adds flac support to osirion.

Improved map menu, implement a 'galactic overview'. Provide galactic coordinates for each zone.
DONE
- add Info record type for zone info
- add Zone location
- add galactic overview to map
- add Zone::info() to network message
- add Zone::flags()
- add Zone::flags() to network message
- add Zone::location() to network message
- add Zone::color() and use it on the galactic map
- add Zone::color() to network message

TODO
- mechanism to request zone map content in multiplayer games
- do not delete client-side ShowOnMap entities in multiplayer games
- show jumpgate links on the galactic map (this requires engine infrastructure)
- mechanism to show only visited places
- map zoom

I propose a key bind(toggle) to allow the ship to be steered via the mouse in the same method as the joystick: directly steering based on relative mouse position(locking the cursor in the center of the screen).

The corrent ui code has default fonts and font size in ui::root().
They have to bo moved to the ui::Palette class and handled like
colors and related settings.

The initial default fonts should be set in the ui::Pallette class.

It might be better to merge ui-style related settings
into a single ui::Stylesheet class and read settings from a .css
file.
