Custom Converters + Converter Syntax

[Absolutionism]

Add a new structure to register a converter of one object to another object,
Example:

register converter:
  from: %classinfo%
  to: %classinfo%
  trigger:
    #code here 

This allows for certain objects grabbed through reflect to be used in either Skript/addons elements or even custom elements.

In combination with this can add an EffConvert that converts the object(s) in a variable to the provided type.
convert %~objects% [in ]to %*classinfo%
Example: (Simple, as I can't think of anything advanced)

set {_var} to block at location(0,0,0)
convert {_var} to a location
{_var}.setDirection()

This allows users to be able to take an object, convert it to a different type, and use whatever reflect elements they need

Finally, add an expression to get all converters (classinfos) for an object + classinfos, either registered through Skript/addons or custom converters.
[all [of the]|the] converter types (of|for) %objects%
Example:

set {_types::*}  to the converter types for a block
#  Output
- ItemType
- Location
- Inventory
- InventoryHolder

This allows users to be able to debug objects, seeing what all an object can be converted to.

We should be sure to add a few guard rails here, like preventing converters to/from Object and ensure that the chaining options are exposed. It's really easy to completely break Skript if you aren't careful with converters.

It also may be a bit tricky to implement as it would require the re-generation of all converters to properly support it in converter chains, which generally is done prior to parsing and locked afterwards.
