New Gui Version and future release

Hello there !

I just updated the version of HO Simu ( in release now so lighter to download ).

THe idea is to compose your work envirronment with windows you want or do not want.
I just recreated what we had with the last version regarding funcionalities ( except now you have an area.lua script for your simulation )

We also lost the 2D version, but I will commit / send it in a few days.

For next release :
- 2D simulation windows OK
- More possibilities regarding the area.lua script ( env definition )
- collisions and detection within the lua script for bots.
- Better management of bots ( to be able to change the script for the bot is the first thing I will do )

This release will be next week ( I will work on it this WE ;) )

If you have any request please send me a message ( for real, just send it I am waiting for people that are actually interested here ;) )
