* CObject Properties
- Added property members to CObjects via `PROPERTY` macro
`PROPERTY(name, get, set)`
- `name`: property name
- `get`: `fun(self): value`
- `set`: `fun(self, value)`
- Prettified `LuaObjectField` struct with unions for function/property value types
- Added properties to `struct ModAudio`
- `position`
- `looping`
- `frequency`
- `volume`
- NOTE: only work with streams- the audio reform will come later
* Define array size only when necessary
- new `__pairs` metamethod for `CObject`s, cycles through all of an object's fields, in alphabetical order
- stray semicolon!
* zip + json properties; check existing file in create file
* smlua_audio_utils_replace_sequence
* audio_stream_load, audio_sample_load, smlua_model_util_get_id

* filepath restrictions
* Some mod_storage improvements
- Cache mod storage files into a map to reduce file I/O
- Fix a bug in mod_storage_save
- Add mod_storage_load_all that returns all keys/values as a table
* shutdown; fix buffer overflow; fix warnings; lua table
* reject binary files starting with MZ or ELF
