Added Deserialization and Serialization for upgrades, only the upgrade manager left.
Fix: Saving a map while having a space in the name no longer crashes the save operation
Fix: Loading objects from a map no longer crashes

Fixed all serialization issues, upgrades now serialize correctly (ad deserialize) so the edit mode is basicly ready except for a few quirks.
You can no longer place bombs on other bombs.
