[Crrcsim-devel] A few updates (3d wind vectors, dialogs, version info)

[<luc...@li...>]

Dear Developers,

I've just pushed a few more updates:
1) 3D wind vectors visualisation mode, toggled from view menu or "w" key; wind 
vectors are drawn in the sky, around the airplane, colored by either total wind 
speed or vertical wind speed (same as in the "Inspect wind" view). It might be 
helpful when flying around (specially on new sceneries) or just to debug the 
wind from terrain computation. 
2) Updated Help-About dialog, showing Crrcsim picture (I've taken it from the 
wiki pages, might be changed). Also added a default callback function to the 
base crrc_dialog class, so that message dialogs which are as simple as the help-
about (but more complex than a simple message box) can be created without 
defining a specific class. The same functionality is used in the updated Help-
Keys dialog, now having a better alignement of the text. Also a new simple 
widget is defined, puaImageFrame, to be used to put icon/images in dialogs: 
used in help-about as well as in location preview. Finally, all dialog 
constructors have been cleaned-up slightly by using the already existing 
crrc_dialog::centerOnScreen() method.
3) Updated configure.ac to derive automatically version information (latest 
tag and last revision  id) to be shown in help-about dialog. I'm not an expert 
on this (just look on web how to do it), but it seems to work ok although 
running autogen.sh + configure is necessary befor compilation in order to get 
the updated data.

Note: all locale need updates

Kind regards,

Luca
