Hello,
Since there was some basic feeatures I trully needed on Blender for game dev, I've put some time to write few scripts
First one allows you to copy the current Transform orientation to origin orientation of one or several objects :

Second one is a easy way to do a bevel-shading using normal edition. All you have to do is select the faces that are not beveled then run the script :

get all scripts here :
http://blenderlounge.fr/forum/viewtopic.php?f=18&t=1438 (these are not add-ons so you have to run them trough the "run python" of the "text editor".)
I'm realy new to blender coding so there's probably lots of coding errors and dirty thing into it, my goal is just to useable tools

Here's more scripts
A texture renamer to match name of the texture with name of the images linked or procedural type :
And a "Vertex Group to Vertex color channel Baker" to ease the vertex color channel workflow
Same link to donwload them, be sure to read instruction : http://blenderlounge.fr/forum/viewtopic.php?f=18&t=1438
Once I'm done I will regroup them to one add-on, if you have any idea for a script, you can ask me by mp or here.
Bound box selection : place the origin to the vertice/edge/face of the objects bound box
UV map to background image coordinates (rotation not supported for now) :
And vertex group selection in VertexPaint mode :
All the scripts are available here with description of how to use them, enjoy
