Configured Gradle javadoc, added distribution archive for portalsearch

- in case it's really used separately

with that most Ant build targets are available native in Gradle build (imho all targets we  really need - see list of legacy Ant targets)

- "readBuildProperties" = see no use
- "init" = not needed (ant internal prop initialization)
- "javadoc" = gradle-task javadoc
- "compile-core" = gradle-task build
- "compile-htroot" = gradle-task compileHtrootServlets
- "compile" = gradle-task build
- "all" = gradle-task build
- "copyMain4Dist" = gradle-task packageDist
- "compileTest" = gradle-task compileTestJava (std)
- "test" = gradle-task test (std)
- "dist" = gradle-task packageDist
- "portalsearch" = gradle-task packagePortalsearch (is that file still used?)
- "clean" = gradle-task clean (std)
- "run" = gradle-task run (std) or shell
- "run-single" = not needed (old stuff)
- "debug" = won't gradleize ide or run
- "stop" = just a shell script
- "create-doc" = gradle-task javadoc
- "distWinInstaller" = won't impl. external tool needed
- "distMacApp" = won't impl. external tool needed
- "deleteData" = hm, won't impl. use nomale system
