(svn r16583) -Update: the order of the language files so it's in sync with english.txt. Normally WT2 would do this, but only with activity for those languages. Now we'd like to the order to match so we can more easily spot import bugs while developing WT3.

/**
* @defgroup dirty Dirty
*
* Handles the repaint of some part of the screen.
*
* Some places in the code are called functions which makes something "dirty".
* This has nothing to do with making a Tile or Window darker or less visible.
* This term comes from memory caching and is used to define an object must
* be repaint. If some data of an object (like a Tile, Window, Vehicle, whatever)
* are changed which are so extensive the object must be repaint its marked
* as "dirty". The video driver repaint this object instead of the whole screen
* (this is btw. also possible if needed). This is used to avoid a
* flickering of the screen by the video driver constantly repainting it.
*
* This whole mechanism is controlled by an rectangle defined in #_invalid_rect. This
* rectangle defines the area on the screen which must be repaint. If a new object
* needs to be repainted this rectangle is extended to 'catch' the object on the
* screen. At some point (which is normaly uninteressted for patch writers) this
* rectangle is send to the video drivers method
* VideoDriver::MakeDirty and it is truncated back to an empty rectangle. At some
* later point (which is uninteressted, too) the video driver
* repaints all these saved rectangle instead of the whole screen and drop the
* rectangle informations. Then a new round begins by marking objects "dirty".
*
* @see VideoDriver::MakeDirty
* @see _invalid_rect
* @see _screen
