#1 Hotkey support for giving orders to units

[Christophe Eymard]

It seems it's a feature that many wanted (me included).

I have changed the default hotkeys that used letters to Control+key, to leave the letters to be assigned.

There are two ways to use it :
by doing
<command shortcut="p">
...
</command>

or, in the building list
<building name="energy_source" shortcut="e"/>

Also, the shortcuts show in the info text of the GUI in-game.

There is no need to map attack, move, or stop, which are binded to "a", "m" and "s" like they were before.
