The enchantments may be serialized to a stringspec and read back from such stringspec.

|
The format for the stringspec is "id=lvl;id=lvl;id=lvl...", with an optional semicolon at the end,
|
|
mapping each enchantment's id onto its level. ID may be either a number or the enchantment name.
|
|
Level value of 0 means no such enchantment, and it will not be stored in the m_Enchantments.
|
|
Serialization will never put zero-level enchantments into the stringspec and will always use numeric IDs.
