In a project with 3000+ Lua files, too much CPU used when saving

[LeRatierBretonnien]

In projects with a lot of Lua files (ie 3000+), the CPU is completly locked by the extension for many seconds (ie > 20). The processing done by the extension should be limited or controllable by a setting to avoid this.

It will take more time to open the project for the first time. In theory, it will be faster when editing and saving. We will debug and optimize the specific situation.
