v0.13 hotfix 1

- Fix version number (only in content.xml, script itself is fully compatible with 0.12 without reiniting AI, so we do not increment $version as well)
- Engineer should not be able to get stuck again in endless loops trying to fix summary when not possible or summary not actives (attention level has to be set and not be one of [nearby, inzone, visible] (not sure about the attention levels to disable)
- Allways use launch_repair_drones even if no drone available or no drone launchpad available, should fix the summary not being updated (gosh, this API is quite unclear!)
- Makes the engineer able to repair non-surface components as well (scanning arrays for exemple, but looks like it can't repair dammaged sections)
