Ap rocket stun and damage consistency and renames vars in rocket.dm

[cuberound]

About the pull request

renames one latter vars in rocket.dm. Makes AP rocket behavior more consistent, AP rocked stuns you for TWICE as longs when it lands on turf under the mob and does not hit it directly. to compensate that I increased the stun duration by 50% to avrage of the turf hit and mob hit. the PR also reduces max distance damage, as it was higer for no aperent reason
but I will not fight agains it if maintainer decides that the values should be diferent, I do not care.

Explain why it's good for the game

expecting 2,6 sec stun and geting 5.3 when someone knows to aim for the tile under you and not you is not fun.

Changelog

🆑
balance: AP rocket applies 3 weaken and 3 paralyze no matter if you hit the mob directly(from 2), at max range (from 2) or tile under it (from 4)
balance: indirect AP rocket does the same damage to walls and mobs
