Add infos to the info manager on loading

[szapp]

Infos (oCInfo) are unarchived from the gamesave. Thus any script injections are ignored when loading. (New game not affected.)

The last step to fully allowing new output units is to hook the end of the oCInfoManager unarchiver and add the respective infos to the sorted list. A local prototype to this solution already works.

Technically this is necessary for

• oCInfoManager
• oCMission deprecated
• oCLogManager not necessary
