[Feature] Make Plugin load order deterministic

[OfficialLambdax]

Is your feature request related to a problem? Please describe. Modders seem to have the issue of not being able to influence the load order of their scripts, which they dont like when one of their plugins requires another.

Describe the solution you'd like Make the plugin loading deterministic (eg. A-Z)

Acceptance Criteria

• Use a std::vector and std::sort it, or use a std::set, here: https://github.com/BeamMP/BeamMP-Server/blob/minor/src/TLuaEngine.cpp#L362 (the sort should be case-insensitive, so the std::sort method may be easier)
