I wanna know if we allow here in eGO the use of scripts like the pistolscript and can somebody guide me to get it?
Well, i didn't see your original question answered, so I thought I'd answer it for you.
Yes.

The engineer is receiving a wrench that allows him to build his buildings faster. It does not allow him to upgrade them and repairs them at the same rate as before, however.
The first suit is as heard of before, giving the spy 90% damage reduction from flames and takes the place of his revolver
The heavy's minigun cone has been tightened
Back in the day when CS first introduced the dual Berettas, it was discovered that they would pretty much fire as fast as you could press the trigger. Me and a buddy came up with two different solutions to get rapid fire out of them.
My friend used right-click as his secondary fire. Since there was no secondary fire for the Berettas, he simply used a script that would remap his right-click to +fire when he switched to his pistols. Then he would feather his left and right mouse buttons like you would a dual trigger set up on a paint gun. It would remap right-click to secondary fire when he switched back to his main weapon.
Since I use right-click for jumping (yeah, I'm weird) his method didn't work for me. Instead I came up with a different solution. When I pressed Mouse 3, it would switch to my Berettas and rebind my mouse wheel up and down to +fire. I had to press Mouse 3 again to switch back to normal weapon switching.
My solution would actually fire faster than his, but it required me to press an extra button. His solution was more automated, but he couldn't fire as fast. The other trade off was that he could sustain his for the entire clip amount, but with my solution it was more of short bursts as I rolled the wheel one way and then rolled it back the other way.
In the end, we both concluded that the dual Berettas were pretty useless anyway, and just stuck with our pistols of choice. In the end, accuracy mattered more than being able to spit out a barrage of bullets.

Of all the listed changes, these stuck out the most:
this makes perfect sense (not) - when you initially build an object (dispenser) it takes a while before it's ready; the new wrench will get it going faster, but will upgrade it more slowly. Can't see this being all that useful, but we'll see...
wow - 90% fire damage reduction? are they serious? why not just give the pyro a foam-dart thrower that says 'NERF' on the side?
So, the heavy will have better firepower at greater distance?
