Test the scripts in Windows and OSX (it's being developed in linux so don't need to check again)
Test the scripts in:
Aegisub v2.1.9 (Commonly used version, should not break as we don't require aegisub.re, may break due to different version of lua)
Aegisub v3.1.3 (Should not break as the lua API is the same as the one in devel environment, but may break on Windows)
