Refactor launch package

[c71n93]

After refactoring launch package in ddr (objectionary/ddr#108) it became possible to refactor launch package here.

The problems here are the same as in issue objectionary/ddr#108. The main problem is importing a global variable from ddr and using it throughout the program.

aoi/src/main/kotlin/org/objectionary/aoi/launch/Launcher.kt

Line 36 in 2db41b1

import org.objectionary.ddr.launch.documents

All this need to be fixed.
