oopsk 1.0 alpha 2 release

alpha 2

Alpha 2 adds some more bug fixes and some more features, like constant fields and getting the template of a struct.

Changelog:

• Adds constant fields: const fieldName: fieldType = defaultValue. These fields can't be changed after a struct is created.
• Adds a SectionExpression for creating structs:

    set {_a} to a result struct with values:
        success: true
        message: "Message sent successfully!"

• Adds a condition and an expression for checking and getting the template a struct was made from: if {_struct} is a "result" struct, broadcast template of {_struct}
• Adds docs (to be posted on skUnity and SkriptHub)
• Adds some more type safety safeguards when getting/setting fields.
