disallow modifiers on the chrome palette

fixes #3123 when the build palette cycles on RA desert maps
remove unneccesary hack-jobs on d2k building icons

now that we have bibs back
remove hackjob on the death hand missile

don't know why Jes did it
it now has the wrong palette applied and looks awful
remove more of Jes's paintjobs where I don't see the benefit

we want smaller installation packages
some alignment fixes made things worse
Merge pull request #3125 from Mailaender/chrome-modifiers
