Add exclude of folders(maybe)

[mundusnine]

The issue is lite-xl cant have more then 2000 files and when we have kinc locally ina project structure we surpass that amount.

We could fix our issue by excluding none-needed system specific files(i.e. if we are on Linux exclude the Windows folder or OSX).

We would do this by adding this to our project module
config.ignore_files = { "^%.", "^node_modules$" }
