Condition factor added with use_condition param in LTX doesn't save properly

[yohjimane]

Describe the bug There is some code in engine which does work initially, but doesn't save properly to packets:

    // Added by Axel, to enable optional condition use on any item
    m_flags.set(FUsingCondition, READ_IF_EXISTS(pSettings, r_bool, section, "use_condition", false));

To Reproduce Steps to reproduce the behavior:

1. Add some log like so in CInventoryItem::Load/Save funcs: Msg("debug - save item %s with condition %f", m_object->cNameSect().c_str(), m_fCondition)
2. load into game
3. drop a weapon/item, shoot it
4. pick it up, save game
5. check logs from step 1 - correct values saved
6. load game
7. check logs from step 1 - correct values saved
8. save game
9. check logs from step 1 - observe bug, loaded values are reset to 1.f (unless the item condition has changed between steps 5 and 7; then it will be equal to 1 - conditionDecremented)

Expected behavior use_condition param should save to packets
